let's say you have a system you're thinking about trying and you want to find the expected win% in order to bet kelley. say the system has gone 70-30 in the last 100 games it said to bet on. how do you go about determining expected win%, do you find the confidence interval at 99% or what? it's been a minute since i had a stats class and i can't figure out how to do this for the life of me...thanks.
