BB Races for Place : 19
BB Placings : 12
BB Place SR : 63%
BB Place Return : $25.10
BB Place Profit : $6.10 (32% POT)

The number of races between wins and placings are different as there was a race with only 4 horses thus NPP.

There doesn't seem to be much different between Best Bets and overall picks but I think over time Best Bets might end up coming out slightly in front.
