BJ Penn vs Matt Serra

BJ Penn's 2-fight experience advantage (6 vs 4 fights) held true, but the algorithm limited the bonus to prevent over-rewarding BJ Penn for the expected result. Had Matt Serra pulled off the upset, his experience disadvantage would have delivered a modest upset bonus.

This was not a title fight, so both fighters received standard ELO adjustments. However, since ELO is a relative system, victories over former champions can have an indirect impact, and Title Fight ELO can differ from Basic ELO.
