Speed Figures
 

I'm re-reading Picking Winners and Beyer on Speed and am contemplating taking a stab at making my own figures.

Does anyone make their own figs and how time consuming is it once you have created the original database of average winning times?

Also is there a FREE source to obtain the charts for a year of races for the NYRA Tracks as that is what I would be focusing on. (After all I'll need to do something after 2/13/08 when Mr. Bruno shuts down Aqueduct.)
