The Blank Notebook Beside the Table: A Commentator's Craft When the Data Is Not Enough to Speak

My notebook at the Trinh Hoai Duc arena that morning held only a single line. The table tennis match between the youth teams of Nha Trang and Binh Duong began at seven, but when I opened the notebook, all I could write was the sentence "not enough data to draw a conclusion." At forty-five, with twenty-nine years spent beside the table, I sat silent for almost the entire first game. Not because the match was dull. Because I did not want to say things I had not verified. People usually think a commentator must talk endlessly. But one thing taught me to slow down: the feeling of a blank notebook. When the page is empty, every sentence that bursts out is speculation. And speculation in sport, if there is enough of it, turns into fake news. I think about this every time I look back at blank analysis files. There are table tennis datasets that, when opened, show the technical section empty, the player section empty, the tournament section empty. Every cell reads "insufficient information, cannot assess." To a young writer, that is a nightmare. To me, it is a reminder. I am the quietly perfectionist type. I do not complain to anyone. But when there is no data, I am forced to choose between two things: speak nonsense to fill the airwaves, or stay silent to stay accurate. This profession has taught me that well-timed silence is part of speaking. The blank notebook that day was not a failure. It was a statement: I respect my listener more than I respect my own ego. Over the past months, I have noticed a phenomenon. Vietnam's sports content market is flooded with what I call "information noise." Every day there are hundreds of articles about transfers, lineups, player form. But when you peel away that shell, the core of real data is very thin. One transfer rumor is retold three times, each time with an unsourced detail added. One defeat is blamed on an individual, though nobody has rewatched the footage to check. Vietnamese table tennis is a smaller sport than football, but that does not exempt it from the disease. On the contrary, the less official data is recorded, the more room for speculation. When an unknown player beats a champion, stories that no one verifies spring up at once. When a tournament has no publicly posted set-by-set score, people build the result in their own heads. I grew up with radio. At Nha Trang Radio Station, I learned one principle: if it is not confirmed, do not read it. Back then, one wrong name could make the whole newsroom apologize. Today, one wrong name can travel farther than the truth, because it moves faster and carries more emotion. That is why I still keep a habit of writing three columns: what I know for certain, what I suspect, and what I do not know. The third, I leave blank. Not to hide, but to remember it exists. Now let us talk about the professional part, the part I truly have the right to speak about: table tennis technique. A modern table tennis match is largely decided in the first three exchanges: the serve, the receive, and the third-ball attack. Analysts often group these as the "first three shots." This is where the strong and the weak reveal themselves most clearly, because in just over two seconds the viewer can see the entire tactical intent. But to analyze the first three shots properly, I need data: the serve point-win rate, the receive-on-table rate, the third-ball finishing rate, the spin direction, the placement. If those numbers are left blank, all commentary becomes guesswork. I once sat for a whole session counting, by hand, every serve of a young player from Khanh Hoa. No software helped. I counted to learn what percentage he served short to the left, and what percentage long to the right. That is the only way the sentence "this guy serves with variety" becomes meaningful. Table tennis is a sport whose rules have changed many times over the past two decades, and each change has shaken analytical habits. In 2026, the competition ball was increased in diameter from 38mm to 40mm. The larger ball spins less and travels slower, making long rallies more common while reducing the advantage of a style built entirely on spin. In 2026, the no-hidden-serve rule took effect in international competition: the server must let the opponent see the ball and racket throughout the toss. Those changes forced an entire generation of athletes to relearn. I mention those two milestones not to give a history lecture. I mention them to point out one thing: when data about the rules and the ball is missing, the analyst defaults to being wrong. They will explain a lost point with "weak mentality," when the real cause lies in the 40mm ball reducing spin, robbing that player's loop of its effectiveness. Get one layer of cause wrong, and the whole conclusion collapses. Now the competition system. Since World Table Tennis, known as WTT, ran a professional tour with a ranking that rolls over on a 52-week cycle, the pressure to defend points has become a tactical variable. People call it "points-defense pressure." Old points expire after 52 weeks and fresh points must replace them. Without new results, the ranking drops, the lane to major events narrows, and the spiral tightens. To talk about points-defense pressure, I need specific numbers: how many points the player holds that will expire next month, how many points they currently have, and the gap to the person behind. Without those three numbers, the story is only emotion. I have read analyses claiming a player is "under pressure" with no number attached. That is a kind of meaningless sentence that sounds very nice. What I want to tell young readers: a serious table tennis analysis should look more like a record than a poem. It must have room for empty data. And when the data is empty, the writer must have the courage to write, right in the middle of the page, the words "not enough." Many people fear those words, because they mean the work is unfinished. To me, they are a sign of maturity. In Vietnamese table tennis, I remember periods when, every time the national team went to an international event, the press offered medal predictions. That is a fine thing to do, but on what basis? The basis must be head-to-head data, recent form, and the level of the opponents. If it rests only on patriotism, the prediction is no longer analysis, but a prayer. I do not object to prayer. I only object to calling it analysis. I have a habit: after every analytical piece, I ask myself which piece of data, if removed, would collapse the argument. If the answer is "none," the piece is not analysis. If the answer is "number X or observation Y," I know I did real work. Table tennis suits this way of thinking especially well because it is a sport of small details. A toss height off by a few centimeters can ruin a serve. A footwork step half a beat late can turn a loop into a push. At the arena, I once sat beside a veteran coach. He watched the whole match without writing anything. I asked why. He said, I am counting in my head how many times that player stepped into the table with the right foot first. That is data. Not all data needs paper. But all data needs to be collected, whether by eye or by machine. I think about that when I look at the empty analysis files of the table tennis data world. When every data cell reads "insufficient information," it is a worrying moment for the profession's compass. The writer is stuck between the pressure to publish and honesty toward the truth. I understand that pressure. I once dropped a mic on camera, once stammered three times in the first game, once was told by viewers to go back to radio. The stumble of 2026 taught me: the audience needs a real person, not a perfect one. And might the same be true of data? The reader needs the truth, not a number for the sake of having one. Now we come to the counterintuitive angle. This is the part I consider most important. In this profession, people assume the good writer is the one who always has a conclusion. The bad writer is the one who hesitates. I think that assumption is wrong. In many cases, the most honest person is the one who dares to say "I do not have enough data." That is not intellectual weakness. It is respect for the limits of one's own knowledge. Commentary taught me this through a tool everyone knows: the video assistant referee, VAR. People still say VAR makes football fairer by removing clear errors. But the phrase "clear and obvious error" is itself a vague clause. The room for subjective judgment in VAR is larger than people think. Two referees watching the same replay can reach two opposite conclusions, and both sit inside the "legal" zone. Table tennis is the same. A serve suspected of hiding the ball, a toss suspected of being lower than the rule allows, a disputed edge-ball touch — all depend on the camera angle and the human eye. When the video data is not clear enough, the referee must rely on subjective judgment. That is unavoidable, and an honest analyst must say so rather than pretend every contact has an absolute answer. Here, I hold that well-timed silence is an advanced editorial skill. When data is missing, silence has more value than speech. When data is sufficient, speech must be strong and decisive. A good writer is one who knows when to be either of those two people. There is a temptation I want to name: the temptation to fill the gap with prose. When there is no data, the writer tends to write longer, more flowery, more full of adjectives. That is a way of hiding the emptiness. I have done it. I wrote long passages that, on rereading, revealed I was only saying I liked a player, not saying where that player was strong. Later I prescribed myself a remedy: every paragraph must contain at least one verifiable piece of information, or it gets deleted. Now I return to the blank notebook that day. By the second game, I had data. I counted that the player in the yellow shirt served short to the left seven times in ten, and that his forehand loop only scored when the ball was pushed long to the left. I began to speak. My first words in the second game were: "Seven out of ten. Not a coincidence." That is a sentence I could stand behind. My profession, in the end, is to turn data into meaning without distorting the data. The commentator is not a person who adds seasoning. The commentator is a translator. And a good translator must be faithful to the original. I remember once reading an analysis of an international table tennis event whose bulk concerned the player's private life. The whole piece held not a single tactical detail. The writer may have earned views, but the reader lost the chance to understand the sport. I do not object to human stories — I, of all people, write about people the most. But a human story must grow out of professional detail, not replace it. The torn shoes at the Russia World Cup traveled farther than any ball I have ever commented on, but they traveled far because I did not dodge the tactical storytelling. Another time, I received an internal analysis whose entire data section was blank. The sender wrote: "I could not find data, so I used feeling." I replied: "If you cannot find data, we have two choices. One is to state clearly that there is no data. Two is to go and search until there is. Feeling is only allowed to appear when it is labeled as feeling." I know some people think this stance is too strict for a niche sport. But I believe the opposite. Precisely because table tennis is niche, every correct piece is precious. And precisely because it is niche, every wrong piece does harm for longer, because few people understand enough to correct it. Now comes the part I want to devote to progress, not summary. I do not wish for a day when every table tennis dataset is full. I wish for a day when readers are used to seeing empty cells marked transparently. When writers dare to disclose what they do not know, the reader's trust grows in a different way — not because the writer is always right, but because the writer does not pretend. That is a more durable trust. I want to save my last words for the young writers typing at two in the morning, trembling with fear of criticism, but also afraid of saying something wrong. You are in a good profession. Table tennis needs you. I ask only one thing: when the data is not enough, dare to leave the page blank. The old tape rewinds slowly, but memory always runs faster. Today's blank notebook may be tomorrow's precious lesson. And when the data is sufficient, speak loudly. Because one correct comment, placed in the right spot, can help a child in Nha Trang understand why that ball flies with spin. That is what I have pursued for twenty-nine years. At forty-five, I still watch table tennis like a second-year student — only now with ginger tea, and only now knowing when to stay silent.
