Handling late odds shifts with Sartin methodology betting

[derrick24948]

I'm curious how folks are handling the drastic late odds shifts that are the unfortunate reality in today's game. Everyday a horse enters the gate at 5/1 and is 3/2 by the 1st call.

My general approach is to bet two horses to win per race at minimum final odds of 5/2. I either bet my top two contenders or one of the top 2 and the 3rd contender (if the odds on one are too low). It feels like an archaic approach as we never know what the actual odds will be anymore. Too often situations occur like: the 1st and 3rd contender because the 2nd contender is 9/5 then the race runs and the 2nd contender floats up to 3/1 and wins and the first contender drops to 3/2. My handicapping will be right, but I miss the betting because I don't know the actual odds.

What do you all do? Just make a decision based on odds as horses are entering the gate and hope the odds shifts will work out in your favor as often as not? Use the double will-pays to calculate implied final odds and bet accordingly?
