Table Tennis, VAR and the Empty File: When Referees Must Rule Without Data

In a national table tennis championship semifinal, the ball clipped the table edge at 9-9 in the deciding set. The line umpire raised a hand, the chair umpire confirmed, and the set closed at 11-9. No high-speed camera, no replay system, no data frame to cross-check against — only the eyes of two people sitting at opposite ends of the table. Spectators argued for days afterwards, but argument without evidence is just noise. A decision that comes with no data is a decision that cannot be verified, and what cannot be verified cannot be defended. I still remember the night in 2026 when I mispronounced the name of Syria's number 9 three times in a row during a World Cup qualifier. Viewers reacted sharply, and the broadcaster had to insert a correction caption during the first half. That wrong name in 2026 taught me that credibility is built through corrections, not by hiding mistakes. Since then, every analysis I publish passes two verification rounds: one for facts, one for the spelling of names and teams. When I applied that principle to refereeing, I found a far larger gap. Football moved ahead by a long stride. From the 2026 World Cup in Russia, VAR was officially introduced. Since then, every incident inside the penalty area can be re-examined through dozens of camera angles. Yet even with VAR, controversy has not disappeared, because technology only supplies images while the interpretation of those images still rests with people. In table tennis, where the ball can travel above 100 km/h and landing points differ by millimetres, that gap is many times wider. The bottleneck for modern officiating lies in the absence of a consistent verification process that turns technology into citable evidence, not in the technology itself. The rules of table tennis, set by the International Table Tennis Federation, are clear about an edge ball. If the ball touches the top of the edge, it is in play. If it touches the side edge, it is out. The distance between the two possibilities is a few millimetres, and at elite speed the human eye can hardly tell them apart. An umpire must rule in under a second, and once the hand goes up, the decision is nearly irreversible. This is exactly where the parallel with pre-VAR penalty-area fouls sits. In 2026, during the World Cup semifinal between France and Belgium, a collision inside the penalty area in the 81st minute went unpunished with the score at 1-0. I spent weeks reconstructing the incident from fourteen camera angles and concluded it was a situation that warranted VAR review. That three-thousand-word analysis drew more than a million views and was consulted by refereeing bodies. The most important lesson I took from it was that the system lacked a clear criteria table to measure the risk level of each situation. I watched 200 World Cup 2026 incidents to find one mistake nobody saw. The biggest conclusion was not that referees are weak, but that the system lacks an anchor point. Without an anchor, each person interprets events in the direction that favours their team, and the debate becomes a war of belief rather than a war of data. Football law is like a whistle: small, but it decides everything. In Vietnamese table tennis, the situation is harder still. National and youth tournaments mostly lack multi-angle replay systems. Umpires work with their eyes, their experience, and their personal reputation. That approach may be acceptable at grassroots level, but at the level that decides places in international competition, it creates real risk. An edge ball called wrongly at 9-9 can change an entire career. No one can give an athlete back the moment that was lost, but organisers can give them a fairer process. One thing few people are willing to admit deserves to be said plainly: adding technology does not automatically make referees better. VAR in football produced new controversies, at times even prolonging the dead time of matches. The problem lies with the person behind the screen and with the criteria set they use to rule. When the criteria are vague, technology merely helps people be wrong more slowly. The counter-intuitive angle sits here. Most spectators believe a correct decision is one that matches their own feeling. But referees do not work by crowd sentiment. They work by the letter of the law, by their viewing position, and by consistency between similar situations. A decision can enrage an entire stadium and still be procedurally correct. Conversely, a decision that pleases the majority can still be wrong if it breaks the consistency established in earlier situations. This is what emotional commentary can never explain, and it is why I choose to write in the form of a ruling record rather than a match report. During two weeks in 2026, when the pandemic halted competitions, I was assigned to draft a procedure for assessing contracts under force majeure for seven clubs in the region. I worked with the lawyers of three clubs, collected forty-five contracts, cross-checked them against international sports law, and completed a guidance document with twelve sections. The biggest lesson was not in the wording of the clauses but in this: when everything is in chaos, the only thing that keeps you calm is a clear process, with priorities and a fallback plan. Referees are the same — composure is not an innate quality but the result of a process trained until it becomes reflex. So where does the solution lie? For Vietnamese table tennis, the first step does not require expensive systems. One high-speed camera positioned behind the table, a review process limited to three decisive situations, and a simple criteria table classifying the risk level of each rally could already change the landscape. What matters is that organisers accept that transparency does not weaken a referee's authority — it strengthens it. A referee willing to say "I called it wrong and here is why" is more trustworthy than one who never admits anything. Mispronouncing a single proper noun is enough to remember that every person's name is a world. For referees, every decision is also a world belonging to some athlete. Stopping the ball is an art; stopping your words is a responsibility. What is worth pondering is the trend ahead. As match data grows denser, pressure on referees will not ease but only rise, because spectators will demand a higher standard of transparency at every level, including tournaments with no live broadcast. The question is no longer whether to use technology, but how to use it so that it serves consistency instead of blurring it. For Vietnamese table tennis, building a verification process now, while the pressure is still modest, is far cheaper than repairing a system that has drifted off standard for years.
