Saratoga's handle gains have been stronger than Del Mar's....

And, no one cares about five furlong track records. I'm surprised you forgot to tout that multiple horses have ran a quarter mile in a world record 20 1/5th over polytrack...which happened at KEE April last year.

Polytrack is a faster surface than dirt if you just want to sprint all-out for very short distances.

However, horses can't stay a distance on it without jogging away the early stages and struggling through the late stages.
