favorites win 28% of races so 50% is wishful thinking.
also prices dont always turn out the way you think either.
the shorter ones (odds on) dont make the 28%.
my suggestion would be to do your homework and trust your judgement
it will reduce your betting and lose less money.

remember the idea of gambling is that over the long term you will lose what the game requires you to lose. unless you are smarter .
