| Experience ELO | 1 143 | 1 080 |
| ELO Change | +32 | -31 |
Irene Aldana's 4-fight experience advantage (13 vs 9 fights) held true, but the algorithm limited the bonus to prevent over-rewarding Irene Aldana for the expected result. Had Karol Rosa pulled off the upset, her 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.

Karol Rosa controlled the striking through overwhelming volume (204 vs 145 total strikes), significant strike advantage (204 vs 145), superior accuracy (58.3% vs 47.1%). However, since Karol Rosa lost the overall fight, her striking superiority couldn't be converted into ELO bonuses.
