Great questions
I stay with lines beaten less than 7.5 I'm just so used to it
Its a habit. I always begin picking lines for horse in a race
using a beginning target speed rating of
80 . I begin with the top 3
class rating horses and morning line favorites. Usually from these horses
I get a good target speed rating number. This target speed rating can be more or less than 80 depending on the race class. I work at using the taget number of the contenders close together.
Anyhow I try to keep as close as I can to the 80 or whatever target speed rating and using lines less than 7.5 in Spec or Val 4 mode
Good Skill
