Late Odds Changes Little question that late odds changes can be very frustrating to us that wager. It's a very delicate issue for the industry as it pits 'perception' against valuable handle.
For us that wager, I've found that the most effective way to predict the finals odds is to utilize the 'will pays'. Take a moment each race and look at the will pays for P4's, P3's and DD's. If a horse is heavily bet in those pools expect that to be the case in the win pool, regardless of the odds a few minutes to post. While not a perfect solution I've found the results will give you very good idea of the 'off odds' in an upcoming race.
