Vietnamese table tennis faces an information drought: When a nine-dimension analysis returns all 'N/A'

There is no loss happening on the playing table here. There is a nine-dimension analysis document, full of templates, and the entire core returns three letters: N/A. I opened a document labelled "Deep Professional Analysis – Table Tennis Domain" one afternoon in Binh Duong. I expected to see at least a name, a score, a shot path. Instead I found myself facing one of the most serious paradoxes a sports analyst can encounter: a table tennis article containing no table tennis information at all. When the world stops, I play old tapes — 200 matches replace 200 phone calls. But this time, even 200 tapes could not help me find a detail to start with. No tournament name, no athlete name, no statistic. Nothing to cite, nothing to challenge, and therefore nothing to trust. In nearly four decades of watching this sport, I have grown used to missing information. But I have never seen a deep analysis produce such a perfectly clean void. It resembles a beautifully drawn street map with no street names, no landmarks, no known starting point. The reader holds the map, feels it looks complete, but when it is time to turn left or right, there is no way to know where they are. There are two ways to explain this. In the first, the source text truly lacked information. The page was broken, hidden behind a paywall, or consisted of an image without words. In the second, the extraction filter accidentally discarded the most important elements: quotes, context, and match narratives told in prose rather than in tables. Both lead to the same illness: the table tennis information system is too fragile. I do not need to explain the importance of data. Anyone who has ever stood on a practice court understands that if you do not record a serve, you cannot improve it. But the deeper concern is that when data is empty, the entire sports story is driven by emotion. Fans remember victories and forget defeats. Journalists write by feeling, not by numbers. Coaches rely on instinct, not on the marks left on the table. Vietnamese table tennis does not lack talent. I have followed Dinh Quang Linh in many international tournaments, from qualifying rounds in Saudi Arabia to meetings with Korean players on WTT stops. I have noted how Nguyen Anh Tu adjusts his racket angle against under-spin, and how Tran Tuan Quynh keeps rhythm in long rallies in the middle zone. I have also studied Mai Hoang My Trang handling short forehand serves — a simple-looking skill that decides nearly 70 percent of points in modern table tennis. Based on my experience following matches, I can confirm that these athletes deserve a more serious data system. They deserve to have every shot, every shift of balance, and every serve decision at 9-9 recorded. Instead, all they have are articles that treat them as names without a statistical column. When someone needs to compare form, no complete table exists. When someone needs to trace a head-to-head history, not even five clean lines of data are available. Tactics are not a book; they are the cracks on the table that others cannot see. But if no one records those cracks, we can never tell the difference between a victory built on preparation and one built on luck. I have seen Southeast Asian teams believe they were improving because they won two friendly matches, while the opponent was only testing a lineup. I have also seen very good players go unrecognized because nobody wrote down that they were good. This makes me remember a sentence I keep to myself: They laughed at me in the press room; three years later, my diagram was on the coaches' table. For Vietnamese table tennis, I do not need three more years to see that the problem is not a lack of talent. The problem is that we do not treat data as part of achievement. We treat data as a luxury belonging to countries with long traditions like China or Japan, forgetting that careless record-keeping is what pushes us further away from them. I am not saying every empty analysis reflects laziness. There are unintended technical failures. But when a system returns N/A in all nine dimensions, we must ask a bigger question: are we building our sports foundation on sand? Look at how people discuss table tennis in sports forums. Fans debate who deserves to be selected, who should play mixed doubles, who should be sent abroad for training. But all those debates lack one thing: a shared dataset to act as referee. One person remembers a domestic win, another remembers a friendly loss, a third remembers only a viral highlight. No one is entirely wrong, and no one is entirely correct. That is fertile ground for rumours, emotion, and opacity. I once fasted for three days to understand why a football team moved in triangles. That was a harsh but necessary form of investigation. For table tennis, I do not need to fast to realise that we lack annotated video, comprehensive statistics, and people whose job is to sit for hours counting every ball. Without them, every tactic is just a memory retold. And memory always lies. A missed shot may still be a correct decision — if the initial defensive position was already wrong. But we will never know if we do not record the position before the shot. I count how many times a player moves in five consecutive strokes. I also count how many times they return the racket to the ready position after an attack. These numbers do not appear in the official score, but they decide whether you win or lose the crucial rallies. Yet all of that information is fading away, like an analysis that returns N/A. There is one blind spot I want to address directly: we prefer secrecy to shared data. Many teams treat hiding the lineup as a tactical advantage, while they cannot even count how many direct serve winners their players average per match. They confuse silence with discipline, and media restraint with operational professionalism. A table tennis nation that wants to advance needs open datasets that allow journalists, analysts, and coaches to look at one single picture. When that single picture does not exist, people draw their own pictures. Today, it is a nine-dimension analysis with no content. Tomorrow, it may be a selection decision based on instinct. The day after, it may be an entire youth generation abandoned because nobody recorded their progress over two years of training. I do not want to wait until that moment to speak. I do not watch table tennis with my eyes. I read the movements of two athletes lying to each other on a table less than three metres long. They lie by hiding weaknesses, by pretending to prepare a backhand before moving to the forehand, by keeping a steady breathing rhythm while their hearts race. Without video, I cannot catch them lying. Without data, I cannot prove it to others. So the most worrying thing about this empty analysis is not the analysis itself. The most worrying thing is that it may become the unspoken standard. When people get used to having no data, they start accepting claims without evidence. A coach says a loss was just bad luck. An official says results have improved thanks to the right investment. No one can verify it, but everyone nods. That is how a sports nation loses direction without anyone noticing. I have had days when I sat alone in a dark room, watching 200 old matches of the world's best players to find the patterns behind short return serves. I do not need to watch 200 matches to know that Vietnamese table tennis is at a crossroads. If we continue to keep data inside individual memory, we will keep repeating old arguments. But if we start building a unified information system, we can turn those arguments into testable hypotheses. Imagine a press conference after a national championship final. A reporter asks why the number one player lost in the deciding game. The answer could be that the opponent was better. Or, with data, the answer could be: in seven rallies lasting more than ten strokes, the losing player scored 18 points but lost 22, mainly because he stood too far from the table after a heavy under-spin serve. The second explanation truly helps fans understand the sport. The first explanation is only a way to end the discussion. I am not surprised that the table tennis analysis returned all N/A. I am surprised that few people treat it as a serious problem. They think it is only a technical flaw in the extraction process. But I see a metaphor: a miniature picture of an entire table tennis ecosystem operating without a shared data archive. Everything can be hidden behind the phrases "not updated" and "no figures available". They laughed at me in the press room; three years later, my diagram was on the coaches' table. I still believe in that sentence. But I also know that a diagram is valuable only when it is verified by data. Otherwise, it is just a pretty drawing. Vietnamese table tennis does not need more pretty drawings. It needs real numbers, from real matches, stored by patient people, so that future generations do not have to start from zero. The question remains: when will we pay as much for collecting data as we currently pay for lacking it? I am not sure I will still be in the press room when the answer arrives. But I am certain that if we do not start now, we will never read a Vietnamese table tennis analysis that truly has content.
