YES!! It would certainly make handicapping an easier proposition, and take the guesswork/insider information out of "trainer intent"
Seriously, I don't mind losing if my horse is not as good as some others, or has a bad day, for whatever reason... but I do have a problem with a horse that gets a "no chance/no effort" trip. Unfortunately, I see that far too often, and my paranoia leads me to think that some insiders were privy to information that I was not.
