I have 627 rounds of disc golf data sitting in a UDisc export. For years I dropped that CSV into a spreadsheet, ran some formulas, and tried to answer a simple question: am I getting better? The spreadsheet worked until it stopped working, which is the thing spreadsheets always do eventually. So I built something better.
The site is called thesearetheholesiknow.com. If you grew up watching Kids in the Hall, you already know why. The nickname is TaTHiK. It is a UDisc data analysis app — you export your scorecards from UDisc as a CSV, upload it, and the app ingests everything into a database and starts telling you things the spreadsheet never could.
What UDisc Gives You and What It Hides
UDisc tracks hole-by-hole scores across every round you play, and it calculates a course rating for each round using the course’s difficulty calibration. That rating matters because score to par alone is misleading. A -2 on a championship layout and a -2 on a short recreational course are not the same round. The rating accounts for that. It is also the bridge to your PDGA rating, roughly: take your UDisc rating, multiply by two, add 500.
What UDisc does not do is analyze anything. You get a table. TaTHiK turns that table into something worth looking at.
What the App Actually Does
Auth, import, and basic summary stats were the first things built, and they work. You upload the CSV once and the app handles the rest — parsing the rows, building out the database, making the data queryable. From there you get the obvious overview numbers: rated rounds, high rating, low rating, average rating, best score to par.
The more interesting layer is what comes after the overview. TaTHiK tracks rating trend over time, so you can see whether your game is moving. It breaks performance down by individual course, so you can see whether you are actually improving at the courses you play most. It surfaces hole-by-hole analysis, which is where the data gets specific: which holes are you playing consistently above or below par across every round you have logged at that course, and which holes are blowing up your rounds when they go wrong. The blow-up hole detector is one of those features that sounds simple until you see your own data and realize you already knew which hole it was going to be.
The coach module uses the statistical picture to generate contextual advice. Not generic tips about grip or release angle. Advice built from the actual pattern in your rounds: cold streak, hot streak, course-specific weakness, consistency problems. It reads your data and talks back to you about what it sees.
Why It Exists Alongside SlingingTheD
SlingingTheD is the practice tracker — putting distance and percentage, disc caddy, course mapping. TaTHiK is the post-round analytics engine. They are sister sites by design. SlingingTheD is where you log what you are working on. TaTHiK is where you find out whether it is working.
The UDisc export does not come through SlingingTheD. It is a direct import from UDisc into TaTHiK. That keeps the two tools distinct and clean. SlingingTheD tracks what happens on the field during a practice session. TaTHiK processes the competitive record.
Where It Stands and Where It Goes
The core is built and working. Auth, import, overview stats, trend analysis, hole-by-hole breakdown, the coach module. What is left is refinement: edge cases in the CSV parsing, polish on the analysis outputs, and a few additional views I have not gotten to yet.
The longer-term question is whether TaTHiK stays a personal tool or becomes something other disc golfers can log into. Multi-user architecture was not the starting assumption, but it is not ruled out. The data the app produces gets more interesting the more rounds feed it. I have 627. Some people have thousands.
For now it is doing exactly what the spreadsheet never could.
