Here's a classic example of the power of Quadrater.
All you have to do is find Chaotic races that are playable. By todays standards, there are many of them to be found, This race was used in hindsight for example purposes.
The pacelines were picked automatically by AOdds
If you look at the top 3 longshot potential ratings you will notice that one of the top 3 were under 4-1 odds and in my opinion would not be considered.
Test it out on past races and you may be very well surprised. Don't expect a longshot in every choatic race to be a winner but horses 4-1 or better win quite often.
BTW look at the top 5 finishers and the LS/P top 5 ratings.
