Thank you for the explanation

It makes more sense now.
I still think it's sexist and need to evolve, though ; granted women scoring above 80 is a recent phenomenon (what do you consider recent, btw ? I feel like Medvedeva was already scoring above 80 in TES, and that was before the previous Olys ; maybe I remember wrong though), but that's what rule changes is all about - taking into account the recent evolutions of the situation and adapt the rules accordingly
And this idea that the women needed their PCS capped at 80% because nobody imagined them capable of jumping multiple ultra-Cs successfully, honestly it just reeks of a glass ceiling situation and insidious sexism to me. You can disagree of course, that's only my perspective, but I'll stand by it
