You may be right but there is also an emancipation of women in all aspects of public life. Women are coming to the fore in everything even being president and CEOs of authority. So while genetic and sexual differences still exist women are probably transcribing slightly more male hormones and proteins in their bodies as they draw closer to equality with men. This is consistent with the blurring of lines between the 2 traditional sexes/genders with increasing modernity. Women start to view themselves slightly differently relative to their male counterparts and this will affect how their nervous systems behave and react.
Perhaps it is under such a psycho social environment that said drugs and supershoes piggyback and steamroll ahead all the women's WRs?
Between drugs and supershoes, I tend to attribute more weight to the supershoes. The drugs work too but not relatively more than the shoes. Between windbreaking pacers and drugs, I also think the former is ahead because of the calming effect it has on the nervous system, kinda like a refuge or sanctuary at least until the penultimate lap. All an athlete needs to do after the penultimate lap is just sprint to victory, very easy. While as for wavelights and drugs the latter is ahead of the former. No matter how good the lights are if your legs and body don't have it (drugs) you are not going to be able to follow the lights.
