Marcin Prachnio vs Sam Alvey

Sam Alvey's 13-fight experience advantage (14 vs 1 fights) held true, but the algorithm limited the bonus to prevent over-rewarding Sam Alvey for the expected result. Had Marcin Prachnio 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.

Sam Alvey earned an early finish with a KO/TKO in round 1 at 4:23, gaining additional bonuses for the first-round stoppage.

Marcin Prachnio controlled the striking through superior volume (36 vs 14 total strikes), solid significant strike edge (15 vs 10).
