Hi Steve
Yes the times are official taken from the PF (Racetech is the operator) and already converted by the lengths per second scale as stated used by the BHA based on the official going (usually done by readings from the Turftrax Going Stick) -

I have attached the Lengths Per Second scale used here , although as i said previously through my own studies i have noticed inconsistencies from what they have stated they "should" be using to what they have actually used.
On Flat Turf the scale should be 6 lengths per second (0.166) on Firm ground to Good ground , 5.5 lengths per second (0.181) on Good To Soft and 5 lengths per second (0.20) on Soft / Heavy. They have separate scales for All Weather Racing and National Hunt Racing.
I basically replicate these conversions so that my figures are in line with the BHA's Official Handicap ratings , as these are a big part of my method of rating.
