Noob here so any help is appreciated. I have a horse with a bsr of 115. I have run a ton of practice races with him but the highest SR he has reached is 107 on a 6.5f fast dirt track, but even when I run the same race and same set up he rarely reaches that level. I have tried numerous distances and surfaces and he seems to average in the 90's. Does this mean I havent found the right age/distance/surface or do horses rarely reach their max bsr. Any help/hints/tips are appreciated.
