Posters should slow down making too big a deal of W K's recent indoor performance. On another thread, I stated in so many words to wait and see.
* Some 5'10" guys are big striders, W K is not. A guy who moves her or his feet quickly and does not take big strides is not going to lose efficiency on the turns as much as a big strider.
* Indoor track engineers, as I have stated designed the tracks for optimum 1500m to two mile performance. A quick striding guy will race well indoors if his fitness is near top form.
* Air quality: Fifty years ago cigar smoking was allowed at M.S.G. for all sport entertainment activities. Air quality at indoor venues today may be better than air quality outdoors. Get an oxygen reading at some of the indoor venues before you say p.e.d.s or super fast shoes.
