When Rules Change Three Weeks Before the Event
Three weeks out. The federation publishes a rule change — maybe a gamjeom rework, maybe a weight-category split, maybe a new protective equipment requirement. Your registration is already open. Your brackets assume the old rules. You have two weekends to rebuild.
Rule changes are normal — rebuilds are not
National and international federations tweak rules every cycle. Poomsae scoring, sparring points, gamjeom criteria, weight category boundaries. You should expect at least one change per year. The question is not "will rules change" — it is "how much will each change cost me?"
Where hardcoded systems fail
If your scoring is a custom script, your brackets are a particular Excel template and your categories are baked into a PDF, every rule change is a manual rebuild. Three days of work, minimum, and usually with bugs that only surface on event day.
Where configurable systems win
A system with configurable category definitions, scoring rules and bracket formats lets you change a setting — not rewrite code. A new weight boundary? Edit the category. A new gamjeom rule? Toggle the setting. A new timing format? Change the value.
When evaluating software, ask: "If WT published a new rule tomorrow, how would I apply it?" The answer should be minutes, not days.
The common rule changes you'll face
- Weight category splits — most common, breaks seeding assumptions.
- Age category boundaries — ripples across multiple categories.
- Point values — changes what counts as a scoring technique.
- Gamjeom criteria — changes penalty behaviour mid-match.
- Equipment requirements — triggers a check at weigh-in, not at scoring.
Your protocol
- Subscribe to federation comms — email + RSS of the rules page.
- Schedule a quarterly "rules audit" in your calendar even when nothing changed.
- Have a test environment — ideally a second copy of the competition system — where you try every rule change before event day.
- Communicate changes to coaches two weeks before the event minimum, with the source link.

The test. If you cannot apply a federation rule change in under an hour, your tooling does not understand rules — it just draws boxes.
