Irene Aldana vs Macy Chiasson

Irene Aldana's 2-fight experience advantage (11 vs 9 fights) held true, but the algorithm limited the bonus to prevent over-rewarding Irene Aldana for the expected result. Had Macy Chiasson 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.

Irene Aldana gained a finish with a KO/TKO in round 3, earning finishing bonuses.

Macy Chiasson controlled the striking through superior volume (72 vs 51 total strikes), superior accuracy (41.5% vs 52.1%).

Irene Aldana's positive striking ELO reflects the overall victory rather than striking dominance.
