The Empty Judge's Chair and the Measurement Limits of Vietnamese Performance Martial Arts

The Empty Judge's Chair and the Measurement Limits of Vietnamese Performance Martial Arts

At the second rotation of a taolu event at a regional multi-sport Games, the organisers set out five chairs for the judging panel. Four people sat down. The fifth chair stayed empty for four minutes and twenty seconds — exactly the length of the routine performed by the Vietnamese athlete who walked onto the floor. Nobody in the arena mentioned it. The electronic scoreboard flashed a few seconds after the athlete bowed, applause rose, and the whole hall turned to the screen. The chair stayed empty.

I was sitting in the press area, fourth row, and I wrote in my notebook: 14:07, chair number five unoccupied, no reason announced. Thirty-three years in this trade have taught me that what is absent usually tells a more accurate story than what is present. An empty chair never lies — it only exposes what we would rather not hear.

The Architecture of a Scoreboard

Wushu taolu, taekwondo poomsae and karate kata share a single scoring architecture. An athlete steps onto the floor, performs a form or pattern for between sixty and three hundred seconds, and a panel of judges at the edge of the mat converts what their eyes see into a number. There is no direct opponent. No knockout. No referee timing a rescue.

In wushu taolu the panel divides into three groups. Group A scores the technical quality of each movement, working by deducting from a ceiling. Group B scores the overall performance — rhythm, power, balance, spirit — also by deduction. Group C scores difficulty, and it is the only group that adds.

Taekwondo poomsae runs almost identically: one portion of the score for accuracy, a larger portion for presentation, all calculated by subtracting errors from a maximum. Karate kata follows the same logic, with technical and athletic criteria and a long list of clearly defined deductions.

Three sports, three international federations, one shared principle: most of the score is given by taking away, and only a small part is added. The system's default position is suspicion of the athlete. You step onto the floor holding a perfect score, and every passing second is a chance to lose it.

For a television audience, this structure is nearly invisible. They see a beautiful routine, then they see a scoreboard, and there is nothing in between to explain why that routine earned 9.32 rather than 9.45. The gap between those two marks is where the entire performance martial arts industry operates, and it is where every argument begins.

What Can Be Measured and What Cannot

Difficulty is the most transparent part of the system. A three-hundred-and-sixty-degree airborne turn has a defined value in the difficulty table. A lowered horse stance has its own value. A jump with a two-level kick has another. A coaching staff can sit down, add those values together, and predict with reasonable accuracy the difficulty score their athlete will receive before the athlete ever steps onto the floor.

The rest is far less transparent. Movement quality is judged by the naked eye, in real time, across a single performance, with no video replay. At most regional events, judges sit five to eight metres away, at different angles, each seeing a different version of the same motion.

Based on my experience tracking matches and performances, I began logging routines frame by frame, marking four moments: the instant of landing after a jump, the actual height of the hip relative to the floor, the knee angle in the stance, and the duration of the balance hold. I did this for roughly thirty routines across the last three Games.

The result drew my attention to a small detail. The difference between the leading group of athletes and the chasing group was not the height of the jump. It was the time after landing. The leading group stabilised back into position in about a quarter of a second, almost invisible to the naked eye. The chasing group needed twice that, and the price was a series of deductions for temporary loss of balance — deductions the audience in the hall never noticed.

What you measure on the screen is not the appeal — it is what you hear in the silence.

This is the fundamental difference between performance martial arts and football. Football, for all its controversies, at least has technology that allows a second look. A video referee can stop play, rewind, measure. Performance martial arts has no such mechanism. Every routine is a single shutter press, and then forever.

There is a further paradox. The sport with the most complex scoring system is the sport that invests least in the tools that would help the audience understand that system. In boxing, you see the scorecards after the round. In gymnastics, you see the difficulty value separated from the execution value. In taolu, you get a string of digits that appears for three seconds and vanishes.

The Technical Profile of the Vietnamese Athlete

The generation of Vietnamese performance athletes has shaped a very clear regional style. Names such as Duong Thuy Vi and Hoang Thi Phuong Giang in wushu taolu, Chau Tuyet Van in taekwondo poomsae, Nguyen Thi Phuong in karate kata, all share a similar technical profile: clean lines, tight rhythm, stable spirit, and a difficulty base held at a safe threshold.

This is a deliberate choice, and it comes from the structure of the competition. At regional level, the point gaps between delegations are very narrow. An athlete with a low difficulty base who barely makes a mistake can overtake an athlete with a high difficulty base who loses balance on the decisive movement. Vietnamese coaches understand this, and they choose the low-risk road.

That road wins medals at regional level. It no longer works at continental level.

In my tracking sheet across the last three Games, the Vietnamese group averaged roughly six tenths of a point below the regional leaders in the difficulty section, but roughly four tenths of a point above them in movement quality. The two gaps nearly cancel each other out at the SEA Games. At the Asian Games, where the leaders' difficulty base rises another tier, the difficulty gap widens to about one point two, while the movement quality advantage stays the same. Simple subtraction produces the result anyone following the sport already knows.

There is another reason Vietnam's difficulty base stays low, and that reason is not on the training floor. A high difficulty base demands a foundation of physical conditioning, sports medicine, injury rehabilitation and a long competitive lifespan. An athlete who trains three-hundred-and-sixty-degree rotations for years accumulates knee and ankle damage in ways a combat athlete does not. Without a sports medicine system behind them, raising the difficulty base means shortening a student's career.

Between the pitch and the virtual arena, the system is terrifyingly alike: discipline makes the hero.

Money, the Calendar, and the Host's Right to Choose

At every regional Games, the host nation decides the programme. This is what makes the SEA Games fundamentally different from the Olympics, and it governs every delegation's investment strategy.

Performance martial arts is a cheap sport. It needs one standard floor, one electronic scoring system, five judges, one secretary and one changing room. No ring, no ringside doctor, no complex doping infrastructure, no medical team on standby. On a Games budget, an organiser can add ten medal events in taolu for the operating cost of a single training mat.

For the same reason, performance martial arts is the easiest sport to cut when a host wants to trim costs. It has no large television audience, no international stars, no sponsor pressure. Whether a performance discipline appears or disappears from a given Games depends on a closed meeting that nobody in Vietnamese martial arts gets to sit in on.

Meanwhile, Vietnam's investment money flows in another direction. The combat disciplines — boxing, wrestling, taekwondo sparring, karate kumite, vovinam fighting — receive foreign experts, video analysis rooms, and long training camps. The reason is practical: combat sports produce clear win-loss results, easy accountability, easy performance reports, easy budget justifications.

Performance martial arts has none of those advantages. When you lose a combat bout, you know where you were hit. When you lose a taolu routine, you receive a string of digits and a gap.

That gap leaves a concrete consequence: Vietnam has no national video archive of performances and their corresponding scores. There is no document a young coach can consult to see which movement was deducted at which Games, by which judge, by how much. Every generation of athletes and coaches starts from zero.

The Names That Get Mispronounced

I have to tell a story about myself. In 2026, at a World Cup, I mispronounced the name of a Croatian midfielder three times in the first half. I was mocked on social media all night. Instead of deleting the post, I spent a month reviewing footage and built a pronunciation table of more than five hundred player names with nationalities, tones and regional variants.

I tell that story here because it repeats itself intact in martial arts competition.

At regional and continental events, Vietnamese athletes' names are flattened over the public address system. Tones are dropped. Syllables are swallowed. Three-part names are shortened to two. Interpreters sometimes read an Anglicised version, and the athlete hears their own name called wrongly at the most important moment of their career.

This is not a matter of politeness. Every mispronunciation is a system trying to say something.

When a system does not take enough time to learn how to say your name, that system also does not take enough time to learn how to score you. The two things sit on the same line. A judge who does not know how your name is pronounced will not know how your style differs from that of an athlete from the same continent.

I misread one name, but the system has misread all of us.

Over the past three years I have recorded how often Vietnamese athletes' names are pronounced correctly at international events. The correct rate does not exceed one third. That figure appears in no performance report, and it never will, because nobody measures it.

The Counter-Intuitive Angle: The Difficulty Trap

After every Games, Vietnamese specialists reach the same conclusion: the difficulty base must be raised.

I believe this is a correct diagnosis of the symptom and an incorrect diagnosis of the cause.

At regional level, medals are not decided in the addition zone. They are decided in the deduction zone. An athlete who raises the difficulty base by three tenths of a point will receive those three tenths if, and only if, the routine is entirely clean. But a harder movement means the body must absorb greater force at the knee and ankle, and the rate of loss of balance on landing grows exponentially rather than linearly.

With a five-judge panel, one visible loss of balance is deducted across several groups at once. A three-tenths gain in the addition zone is wiped out by two one-tenth deductions in the subtraction zone.

That is the arithmetic. But the real problem lies elsewhere, and it lies with the chair.

Vietnam has no judge sitting on the continental technical panel. Vietnam also has no real-time opponent scoring analysis unit in any martial arts federation. Meanwhile, the regional leaders already run two-person teams sitting in the stands with laptops, re-scoring every opponent routine against the exact criteria the judges are using, and sending the results down to the technical area before the next rotation begins.

That is the real gap. Not the height of the jump. The presence of someone taking notes behind the stands.

We learn nothing from what goes right — only from what falls out of rhythm.

What Remains After the Applause

After the scoreboard goes dark, the organisers lower the board, the audience leaves the arena, and the fifth chair is folded away with the others. The next day it is set out again. The day after that, again.

A performance martial arts culture that wants to exceed its own measurement limits must begin by measuring what nobody has measured: how often its athletes' names are pronounced correctly, how many judges it has on the panel, how many routines are archived with their scores, how many people sit in the stands with a criteria sheet open on a laptop. Those figures never appear on the electronic scoreboard, but they determine what the electronic scoreboard displays.

The empty chair is still there. It is not angry, it does not accuse, it does not demand. It simply keeps exposing, once every Games, what a martial arts culture has chosen not to see.
