Three Scoring Logics in Martial Arts and the Data Gap Vietnam Has Yet to Fill

Opening: A Kick That Left No Trace

In the second minute of extra time, the fighter in red spun and threw a roundhouse kick with his right leg, making contact with his opponent's left hip. The sound of the impact was loud enough that the fans in the last row could hear it. The head referee, standing four meters away, raised his hand to award a point, then lowered it again. Three judges at three corners of the ring looked at the small screens in front of them at the same moment, but those screens only showed a live feed, with no slow-motion function.

When the final bell rang, the scoreboard showed 29-28, 29-28, 28-29. The winner was the fighter in blue, the man who had just taken a kick that almost the entire arena had heard. At the press conference, one judge explained that he was not sure whether the kick had landed. No one could prove otherwise. There was no footage of sufficient quality. There was no record of the moment he made his judgment.

I was sitting in the fourth row, notebook open. The only thing I managed to write down was my own feeling. An analyst who can only record his own feelings has already failed at the first column of the page.

That is why I am writing this piece. Not to retell a single fight, but to point to a larger gap: martial arts, from village courtyards to Olympic arenas, operate on a scoring system that even those inside the sport cannot explain consistently. When a decision leaves no trace, it cannot be reviewed. And what cannot be reviewed cannot be improved.

Context: Three Streams, One Tangled Scoring System

Vietnamese martial arts stand on three different streams, and each stream carries its own scoring logic. The first is traditional martial arts and traditional combat disciplines such as Vovinam, where points are awarded based on the precision of techniques, balance, and control over the opponent. The second is boxing, where scoring follows the mandatory 10-point must system: each round, the winner receives 10 points and the loser receives 9 or fewer. The third is sanda and modern combat sports, where points accumulate for each valid strike, with bonus points for throws.

These three streams have never been placed side by side in a systematic way. A boxing referee is trained to count clear strikes and assess round control. A traditional martial arts judge is trained to look at posture, balance, and the aesthetics of techniques. A sanda referee is trained to distinguish valid strikes from blocked ones. When these three sit at the same table to score a hybrid bout, they speak three languages with no shared dictionary.

While following domestic and regional martial arts events over many years, I noticed something worrying: the number of tournaments is growing faster than the number of properly trained referees. Grassroots events, youth events, and open events appear every month. But scoring procedures, evaluation standards, and cross-check mechanisms have barely moved. This creates an ever-widening gap between the pace of the ring and the pace of the officiating apparatus.

That gap is not Vietnam's story alone. It is the story of the entire global martial arts world, where three scoring logics coexist without a common standard. But in Vietnam, the gap is more visible, because we imported all three logics at once without first building a data foundation thick enough to distinguish them.

Core: Three Logics That Cannot See Each Other With the Same Eye

The First Logic: Combat — Points and Balance

In combat disciplines, what is measured is not the number of strikes, but the degree of control over the bout. A fighter may throw twenty strikes in a round and still lose to a fighter who throws only five, if those five carry more weight and put the opponent on the back foot. This is the core principle of the 10-point must system: the score reflects effectiveness, not quantity.

The key point is this: the system measures something that cannot be counted directly — control. Control only emerges through the subjective judgment of the scorer. And because it is subjective, it depends on angle, on distance, on whether the scorer saw the decisive moment.

I once spent months analyzing footage of combat bouts and discovered a simple pattern: the greater the distance between two fighters, the higher the scorer's error rate. When two fighters are close, the referee can clearly see both the strike and the reaction. When they are far apart, the referee must judge based on overall movement, and that judgment is far more error-prone. This explains why long-range strikes are always the source of controversy.

The Second Logic: Performance — Difficulty and Quality

In the performance stream, everything is reversed. Points do not come from the opponent but from the routine itself. Judges here are divided into groups with different tasks: one group scores technical difficulty, one scores execution quality, one scores overall impression. The final score is a composite of several independent scales.

This logic has one strength: it can compare two routines performed at different times. It allows scoring based on predefined standards, rather than depending on whether two athletes are on the mat at the same moment. This is an advantage the combat stream lacks.

But it also has a fatal weakness: it measures something that has already been defined. When technical difficulty is written into the score sheet, athletes tend to optimize for that sheet rather than for real combat effectiveness. A beautiful, difficult movement that matches the scoring criteria may be entirely useless in an actual combat situation. The gap between the beautiful and the effective is a paradox the performance stream has never resolved.

The Third Logic: Sanda — A Hybrid With No Home

Sanda is the most interesting case, because it stands between two streams and carries the contradictions of both. It allows punches, kicks, and throws. It accumulates points per valid strike. It also has its own performance component. In theory, sanda is the perfect combination of combat effectiveness and showmanship.

In practice, sanda creates a third logic that belongs fully to no one. A throw in sanda scores higher than a landed punch, because it demonstrates greater control over the opponent. But the way a throw is evaluated is closer to the traditional stream than to boxing. As a result, a sanda referee must master three sets of criteria at once: combat criteria, performance criteria, and grappling criteria.

This leads to an important conclusion: the three scoring logics of martial arts cannot be unified by simply adding criteria together. They operate on three different philosophies about what constitutes victory. The combat stream believes in control. The performance stream believes in standards. The hybrid stream believes in synthesis. Trying to place them on the same scale is like trying to measure temperature with a tape measure.

The Data Gap: What No One Measures

In boxing and modern combat sports, people have begun collecting data in great detail. Strikes thrown, strikes landed, accuracy rate, evasions, distance traveled — all can be recorded by motion-tracking systems. This data allows bout analysis at a level the human eye cannot achieve.

But in the traditional and performance streams, almost no data is collected systematically. No one measures strike speed. No one measures impact force. No one records the moment a judge makes a decision. No one stores scoring records in a retrievable format. The result is that every controversy ends in words, not numbers.

I once attended a seminar on refereeing, and what struck me was that no one in the room could answer a simple question: over the past season, what percentage of decisions were disputed? No one knew, because no one measured. A system that cannot measure itself cannot repair itself.

Vietnam's martial arts data gap is not a lack of technology. It is a lack of the habit of record-keeping. We have cameras, phones, and computers. But we lack a process to turn those images into analyzable data. And without data, every controversy remains forever a war between different memories.

VAR in Martial Arts: Technical Limits and Legal Limits

Many people think the solution to every scoring controversy is technology. Install cameras. Use slow motion. Let machines decide. But technology does not automatically create fairness, because technology can only answer questions that the rules have already defined clearly.

In football, VAR works because football rules define very clearly what offside is, what handball is, what a foul in the box is. The machine only needs to check whether the event on the pitch matches the definition in the rules. But in martial arts, the rules do not clearly define what a valid landed strike is. Does a punch that touches a blocking arm count as landed? Does a kick that lands but does not move the opponent count as effective? These questions have no unified answer.

When the rules are unclear, technology only makes controversy sharper; it does not make it disappear. A slow-motion clip can show that a kick landed, but it cannot tell the judge how many points that kick deserves, because that scale has never been defined in enough detail. VAR in martial arts, if adopted, would only move the controversy from the corner of the ring to the control room. It would not solve the root problem.

Every slow-motion replay is a surgery: cut right, cut wrong, but never cut in haste. In medicine, an operation only succeeds when the surgeon knows exactly what he is looking for. In martial arts scoring, the judge is the same. If he does not know exactly which criterion he is looking for, then even with hundreds of camera angles, the result will still be a vague judgment dressed up as precision.

Ring Pressure: When the Noise Disappears

During the period when tournaments had to be held without spectators, I had the chance to observe a rare phenomenon. When the cheering disappeared, the pressure on the scorer changed in an unexpected way. With no crowd roaring after each moment, the scorer was no longer swept up by collective reaction. They decided more slowly but more consistently.

The empty arena of 2026 did not lighten the referee's load; it laid bare every judgment before the silence. When there is no noise to lean on, the scorer must face his own criteria. And what was notable was that in many cases, they still erred in the same way as when the crowd was present. This shows that scoring error does not come from the crowd. It comes from the criteria themselves, which are not clearly defined.

In martial arts, crowd pressure is even greater than in football, because spectators sit closer to the mat and react more immediately. A referee standing between two fighters, a few meters from the stands, bears a double pressure: pressure from the two fighters trying to score, and pressure from the crowd trying to impose its expectations. Anyone who has stood in that position understands that the right decision is not the easy one.

The Counterintuitive Angle: Emotion Is Not the Enemy of the Rules

The usual reaction to a scoring controversy is to call for emotion to be removed from judgment. Let the rules speak. Let machines decide. Let humans step out of the controversy. It sounds reasonable, but it rests on a false assumption: that rules and emotion are opposites.

The opposite is true. Rules are made by humans, and every rule carries a hidden emotion. The rule against striking sensitive areas exists not because a machine says so, but because humans feel pain when they see it. The rule that awards high points for a throw exists not because it is more technically effective, but because it creates a stronger sense of control. Emotion lies at the root of every rule; we have simply stopped seeing it.

What is worrying is not that emotion is present in judgment. What is worrying is that emotion is present without being recognized. A judge who admits he is influenced by a fighter's demeanor is still better than a judge who believes he is completely objective. The first can self-correct. The second cannot, because he does not know what he needs to correct.

I never say the referee is wrong. I only say his view did not have enough light. In martial arts, that light is not just the physical light of the ring. It is the light of clear criteria, complete data, and documented process. Without that light, even a good judge can make a decision he himself cannot defend.

The biggest blind spot of Vietnamese martial arts is not individual referees. It is that we have never built a system that allows referees to see themselves. We punish error, but we do not teach how to see. We argue over results, but we do not argue over process. And a martial arts scene that argues only over results and never over process will repeat the same mistake forever.

Conclusion: Three Scenarios for the Next Ten Years

The first scenario is the scenario of continuation. Tournaments keep appearing, controversies keep erupting, and everything still ends in words. The data gap widens, and the audience's trust thins. This is the most likely scenario if no one takes the initiative to change.

The second scenario is half-hearted technological adoption. Big events install cameras and use slow motion, but scoring rules remain vague. The result is that technology becomes a tool to justify old decisions rather than a tool to check them. This is the most dangerous scenario, because it creates an illusion of transparency.

The third scenario is standardization from the ground up. Before installing cameras, define clearly what a valid landed strike is. Before using VAR, build a verifiable criteria table. Before arguing over results, argue over process. This is the hardest scenario, because it requires federations to accept that the problem is not the referees but the system they operate.

In the next ten years, the question is not whether Vietnamese martial arts uses technology. The question is whether we dare to record ourselves. A martial arts scene that dares to record itself is one that can mature. A martial arts scene that only dares to record its opponents will forever stand still in a loop of controversy.
