Have just done a little finetuning and only betting on Wed & Sat get the following data :-


Observed successful lay selections =

Total Lays * (1-Win SR) = 427*(1-.13) = 371

Expected successful lay selections =

Total Lays * 1-(1/Average SP all selections) = 427*1-(1/10.21) = 385

Advantage = (371/385)-1 = -0.036
