Gulfstream has been at it's current configuration for three years now. I think there is a large enough sample size to come up with legit par figures. Oaklawn, Fair Grounds have been the same for a long time.

As far as the So. Cal tracks I would like to see a larger sample to get a true fig. The Proride surface was installed last summer at Santa Anita so we're working with 3+ months of data of info. I don't think that's enough info.
