Polytrack temperature relationship

[joeydb]

I heard the first hour Wednesday on ATR, where Steve shared the observation that a cool or damp polytrack surface seems to play more "fair" where speed horses have a chance on par with other surfaces, and that on the contrary, a hotter polytrack surface gives a better chance to off the pace runners and closers and punishes speed horses.

I found that very interesting, and I further wondered whether the recent practice of watering the polytrack has cushioned that relationship to where the effect of the hot weather would be delayed or alleviated through watering, or whether the "hot poly" course is still punishing to speed.
