The converter basically accounts for the value of a beaten length being more significant on synthetic tracks. Using it for Derby preps for example...

Pioneer of the Nile's '09 Beyers of 95, 90, and 96 become 100, 93, and 101.

Papa Clem's 94 in the San Felipe becomes a 99

Chocolate Candy's last two numbers of 91 and 94 become 95 and 99

General Quarters 95 in the Blue Grass becomes a 100

I Want Revenge's 92 in the Bob Lewis becomes a 96.

The Pampelmousse's 103 in the Sham stakes becomes a 111


Anyone who bets on races at cheaper tracks knows that synthetic track numbers are greatly inflated when slow horses are involved. The opposite of what happens with the fastest horses. A 45 on synthetic is equal to only a 33 dirt.

Thanks for posting this. Ashamed to admit I wasn't aware of pacefigures.com. Looking at the conversion values, it's clear that any Beyer speed fig on synthetic can be converted to the dirt equivalent by:

DirtFig = SynFig + (SynFig - 80)/3

Using The Pamplemousse's 103 in the Sham as an example, you'd have:

DirtFig = 103 + (103-80)/3, or

DirtFig = 103 + 7.67 = 110.67, which rounds to 111.

It works for Beyer "SynFigs" below 80, too.
