Female are relatively poor at onsight and flash

In comparison with other physical sports, female climbers' performances are really close to the male's. The best example is Ashima Shiraishi and there are probably about 100 female who do at least an 8c Route or an 8A Boulder every year. However, when it comes to onsight and flash, female are relatively poor and it is rare that we see 8b onsights or 7C flashes. Nice exceptions to this are the 8a ranking game onsight/flash leaders, Laura Rogara (15), with eleven 8a to 8b onsights, and Karoline Sinnhuber, with seven 7C to 8A flashes. Being in the top-10 female boulderers in the world you need to do ten 8A's yearly but at the same time, you just seem to need to flash ten 7B+ or harder Boulder problems. When it comes to Routes, it is probably enough to onsight ten 7c's to be in the top-10, which seems easier than to redpoint ten 8b+'s or harder.
