A couple years back I discovered nearly every winner had a Brisnet LP of 95+ and about 80% of second place finishers had same. It's really just a lazy handicapper's version of the Stanley Caris final 3/8th fraction method. The impact fell off significantly in the show pool. Definitely something to consider when playing the exacta however there will be quite a few of them this year.
I agree. I use it as an angle. I wouldn't suggest picking just based on that criteria alone.
