Field size has shown the major correlation. An increase in 1.0 horses translates to a 10% change in handle. OPX field size was up by 0.5 horses and their handle was up 4%. GPX field size was up 0.5 horses and they increased handle by 5%. Conversely, Hawthorne lost field size appreciably this year and they will see a major reduction in handle, as Turfway saw this year. Hawthorne dirt, TPX poly: Same metrics when it comes to field size.
