I can only hope that you are joking. Or do you actually believe that you can look at an elite runner and tell at what weight they would do their best running?
You're being really emotional and letting the first voice that pops in your head make you look a bit childish.
My point is that weight is often more important than mechanics, but going beyond a certain level of leanness is just not possible for most people. Jeptoo is able to sustain an extremely low level of bodyfat. If Deba, or Dibaba, or damn near any of us for that matter, could sustain the same low level of bodyfat as Jeptoo AND stay healthy they/we would be faster. That's simple.
If Jeptoo puts on 2kgs of fat, which would put her in the same bodyfat percentage realm as most of her competitors, she would run nearly 5 minutes slower, and of course be forced to take a risk in changing her mechanics or finding another way to make money.
