The Empty Spreadsheet and Vietnam Swimming's Data Problem

I opened my familiar Excel file at 6 AM, expecting a long list of performance data. The screen showed an empty table. No athlete names, no technical metrics, not a single row of data to begin with. My Saigon coffee was still warm in my hand as I sat there for nearly ten minutes, staring at the vast whitespace like a pool with no lane lines. This week's sports events had no new records, no tactical surprises, no performances that made the nation hold its breath. What I received from the data source was merely an empty analytical framework — nine layers of methodology, twelve assessment tables, all displaying the same message: insufficient information. For someone who has worked as a swimming analyst in Vietnam for over a decade, this scene is all too familiar. It is a chronic illness of an entire sports system. DEEP ANALYSIS To understand why an empty data table accurately reflects the reality of Vietnamese swimming, one must examine how this sport operates structurally. In strong swimming nations like the United States, Australia, or China, every athlete from a young age is attached to a continuous data profile: results across distances, split times every 50 meters, stroke frequency, underwater efficiency, recovery metrics. In Vietnam, such data exists fragmented, largely stored in individual coaches' notebooks, unstandardized, unarchived, nearly inaccessible for independent analytical purposes. The consequence is a paradox: analysts like me specialize in swimming, yet must work with such scarce sources that every number we obtain is as precious as gold. We cannot determine which phase of the developmental curve an athlete occupies — surging or plateauing — because there are not enough continuous data points to plot a trajectory. We cannot compare across generations of athletes because standardized data from different eras is lacking. This emptiness is particularly severe when considering the concept of the puberty barrier. In world swimming, many teenage female athletes achieve outstanding results before puberty, then suddenly disappear from the competitive map. Data-driven systems can identify these risks early and adjust training plans accordingly. In Vietnam, doing so is nearly impossible — we lack sufficient data to know which athlete is in a sensitive transition phase, who needs technical adjustments, who should switch race distances. LESSONS FROM STRONG SWIMMING NATIONS Across 16 years of industry observation, I have noticed that the gap between Vietnamese swimming and the world lies not in physicality or willpower, but in information infrastructure. Consider the American selection rule: the Olympic Trials occur once, and the top two finishers in each event earn their spots. This rule creates enormous pressure and occasional upsets — a world champion can be eliminated at the national trials. But Americans accept that risk because they understand the long-term data of an entire system rather than a single day's performance. When examining a competition result, analysts must determine its reliability: is this a one-time breakthrough or the product of years of stable progression? With only a single data point, that question cannot be answered. World swimming has witnessed countless cases of athletes producing exceptional performances at one meet, never to repeat them. Inexperienced analysts rush to label them prodigies; veterans know that one number does not make a career. The high-tech swimsuit era of 2026–2026 is the greatest lesson in how data can deceive. 43 world records fell at the 2026 Rome World Championships, many achieved solely through full-body polyurethane suits. When the suits were banned in 2026, analysts had to filter out that entire period to determine each athlete's true worth. If Vietnamese swimming once had a period of performance distorted by equipment factors, we can never know — because no data system exists to cross-reference. THE CONTRARIAN VIEW There is a counter-intuitive realization I have reached after years of working with Vietnamese swimming data: the absence of data is not merely a weakness, but also a honest mirror reflecting our priorities for this sport. Sports media cannot comprehensively report domestic swimming achievements because competitions lack standardized measurement systems. Sponsors hesitate to invest because no metrics prove athletes' developmental potential. Fans gradually lose interest because no tactical stories are told through compelling numbers. This creates a vicious cycle: no data → no analysis → no media coverage → no investment → no development → even less data. For an analyst, escaping this cycle does not come from waiting for the system to change itself. It comes from starting to record — even a single provincial youth competition, a single club, a single group of athletes. In 2026, I began building a manual xG database for football from scratch after losing money on a bet based on emotional advice. Similarly, building a national swimming database can begin with a small group of dedicated people, recording a few results each week, compiling a report each month, creating dataset long enough within a year to reveal trends. When I received the empty analysis table that morning, my first reaction was disappointment. But after reflection, I realized this was not a meaningless outcome. It was an accurate diagnosis. It says we are facing a structural problem, not an isolated incident — and structural problems require systematic solutions. The question now is not how to analyze Vietnamese swimming with existing data. The question is: who will lay the first brick to build that database? Who will record the results of the next competition in an organized manner, share them with the analytical community, and turn a small dataset into the foundation for sound future decisions? Every young Vietnamese swimmer today deserves to be recorded in a national data system. They deserve to be evaluated by scientific analysis rather than adult emotion. They deserve a career journey that is fully tracked — from the first kick to the pinnacle of their sport. Thousands of hours of training in the water, hundreds of nights racing in the blue lanes — all deserve to be recorded, analyzed, and known. The greatest lesson I have learned is not from numbers that speak, but from numbers that do not exist. Emptiness is not the end of analysis. It is the beginning — an invitation for us to fill the blank spaces together, one number at a time. My coffee had gone cold in my hand without my noticing, but the empty pool before me had finally sketched the outlines of lane lines — boundaries that will be created by the very hands of those who believe that Vietnamese swimming deserves to be seen clearly. 2,400 matches once whispered in my spreadsheets — now it is time for the voices of Vietnamese swimmers to begin rising, clear, transparent, and impossible to ignore.
