DRF:
TRACK BIAS- A racing surface that favors a particular running style or position; horses that run on the lead or on the rail.
This seems to combine energy conservation and expenditure and physical positioning. The question is if those all belong together, especially if they can occur independently.

I don’t disagree that there are n-number of biases that affects a horse’s race performance, but the 4 major measurable biases that invariably affects a horse performance during a race and ranked in terms of impact when they occur are:
• Aerodynamic drag (air resistance) – this is a biggie because the racehorse has a longitudinal drag coefficient of about .60 with the aerodynamic abilities of the horse measured using the horse’s coefficient of drag.
• Wind Resistance is the next adverse force confronting the horse’s performance, but its impact is inconsistent due to the weather changes.
• Turn Impact can change a race very quickly; particularly when the air resistance is added in.
• Lastly the surface resistance will have an impact; especially when the track surface is soft (turf or dirt) and deforming when under pressure. This also increased the resistance to motion.
