if i could find evidence that all of the tracks across the country are much, much slower than they used to be, i would be more willing to buy the fact that horses run 10-15 lengths faster than they used to at 10f. even then, i would take 'bid or affirmed against todays speedballs at 10f if i was getting 10-15 lengths.
