Yes I did for a while, but unless you know what's in the trainers mind, it all evens out in the end.
Since it's impossible to say what would've happened if certain actions were NOT taken I'd say this is just another variable we can do without.

Many times the horse is just not good enough and the trainer experiments without a clue.

Now to contradict myself, if a horse has run close many times without additional gear, and suddenly wins with some gear, I'd be careful backing it when the gear is removed!

Good luck

Ps. I listened to Bart explaining too, but I have the feeling it was just smoke screen, the horse had a better than good chance anyway.
