10.49 predicts sub 21 or thereabouts, but if you discount that time as wind aided, then Flo Jo's best 100m still equates to 21.22. Either way, the women's 200m record is weaker than the women's 100m. Yet, even the 100m record is under threat with Herah's 10.54 last year and a lot of recent Jamaican times under 10.70 indicate it is under threat. 800s are not that hard to pace, but you don't have anyone around to push anyone to the record. When you've had record-capable athletes like Semenya or Jelimo, they've not had races with comparably fast runners. Jelimo ran 1:54 then disappeared. Semenya after the early 1:55 was apparently sand-bagging or using blockers until the champs. Can anyone push Mu below 1:55? The funny thing is that you'd think that steroids would have helped the Eastern European dopers more in the power events of 100-200-400 and weights than the 800m.
