> That 5% is static - individual guys can improve their chances of being in the 5%, but that pushes out others already in the 5%.

Why makes you think that? It seems much more likely to me that women are selecting whatever profiles that interest them, which would be >5% if potential matches made better profiles. I've seen the women experience of dating apps from women friends, and indeed men profile quality is abysmal (my bisexual and lesbian friends seem to swipe on a much higher proportion of women profiles FWIW), to the point that 5% even seems pretty high once you also take into account personal preferences.
