I saw you posted on a video a few months ago that 'the video was great but it missed one thing..girls'. And i believe azun responded with an argument i entirely agree with. Why should you girls get more respect for achieving quite mediocre combos just because you are girls?
It's the same reason the EPL, NBA, etc are never mixed genders. Males have better body types to suit these sort of things. Of course both genders can do any thing they like/want but when it comes to the physical aspects, it's clear that males have the advantage. Hence why it would be unfair to put WNBA players in the NBA and why a mediocre combo would be a good achievement for females.
But one thing, the female average level is WAYYY lower than it could be due to them doing LPs and not 'needing' to push themselves. Like Billy Wingrove.
To answer the OP question, obviously it's more/smarter training. For example; When warming up, make sure you have your warm up goals. For me it's 10 htws before I move onto 10 hatws before I move onto 16 move combo etc. This will keep your average higher and when you want to try harder, you'll always do better than your average meaning you'll improve indeffinate.
