Answers to commonly asked questions
GengMantap uses an all-positive rating system inspired by Elo, the same system used in chess and other sports worldwide. Every team starts with a rating of 1500. Your rating always goes up when you play a match â winning gives you a bigger increase, while losing still gives you a small participation reward.
Every new team starts with a rating of 1500. This is a neutral rating that allows the system to calculate the team's true strength after a few matches.
Winners get a large increase (+8 to +40), losers get a small participation reward (+2 to +5). The amount depends on: (1) Rating difference - beating a stronger team = bigger bonus, (2) Goal margin - winning by more = more points, (3) Match type - competitive gives more than friendly, (4) How competitive the loss was - close losses get more than blowouts.
No. Every confirmed match gives you positive rating â even if you lose. Your rating can only decrease through inactivity decay (not playing for a long time) or admin adjustments for violations.
K-Factor controls how much the win bonus can change per match. New teams (0-9 matches) have K=30 for faster rating discovery. Experienced teams (30+ matches) have K=20 for more stable ratings. The maximum total rating change is +40 per match.
