AngryPixie, the POT refers to liability. Today I had a liability POT of 17%. My first two races lost, but only a total loss of $0.96.

There's only been a paltry 35 races since I started this particular system from last Monday. However, there's slightly more than 200 races since I began laying the field, continually experimenting to improve the system until I was satisfied, which I think I am now.

Over these 200-plus races the liability POT was about 6%.
