How scoring works

NCGA uses an Elo-style rating system, similar to chess and competitive gaming, to rank athletes within each weight class.

The Basics

Every athlete starts with a rating of 1,000 points. After each recorded match, points are transferred from the loser to the winner based on:

  • The rating difference between the two athletes (upsets are rewarded more)
  • The method of victory (dominant wins earn more points)

Win Type Multipliers (K-Factor)

Win Type K-Factor Description
Pin 40 Submission or pin — maximum points transferred
Tech Fall 36 Win by 10+ point margin
Major Decision 32 Win by 8–9 points
Decision 28 Standard points win
Default 24 Opponent unable to continue
Forfeit 20 Opponent does not compete

The Formula

Expected score = 1 / (1 + 10^((Loser Rating − Winner Rating) / 400))
New rating = Old Rating + K × (Actual − Expected)

"Actual" is 1 for the winner, 0 for the loser. The minimum rating is capped at 100.

Example

Athlete A (rating 1,050) defeats Athlete B (rating 980) by Pin (K=40):

Expected A = 1 / (1 + 10^((980−1050)/400)) = 0.60
A gains: 40 × (1 − 0.60) = +16 pts → new rating: 1,066
B loses: 40 × (0 − 0.40) = −16 pts → new rating: 964

If B had upset A (lower-rated wins), the point swing would be larger — upsets are rewarded more.
