I don't know... you would need to ask the horse.
I guess some horses go faster, others resent being hit.
Now getting back to the question... You are like the Brodie, never answer a question, when you are backed into a corner and wrong, which is often. Brodie claimed that The Fixer should have been disqualified because Natalie Rasmussen was charged with excessive whip use and that Tiger Tara should have been promoted to winner. I pointed out that McCarthy the driver of Tiger Tara was also charged with excessive whip use. If The Fixer ought to be relegated according to Brodie, then so should Tiger Tara for the same offence. That would make the third horse the Cup winner.
Personally, I would ban whips.
