I've been preparing to do some nba push charts and was reviewing j7's book to make sure I didn't forget anything and I got stuck. Pg 246 he makes EV .013 the math appears to work but I don't know how you get it? I've always used decimal odds for my calculations 1.90909*.53=1.0118.
book math | (0.53)(1)-(0.47)(1.1)=.013
also from me | (0.53)(0.90909)-(0.47)(1)=.0118
Am I missing something regarding odds-on prices here? I'm trying to figure out a way to do push charts using euro style odds.
