10+1 sng. $110 entries, $100 prizes. -10/110 = -9.09%
so thats the average return. where is say it might not be "quite" that # is because perhaps there are more than 50% that do better, but a few big losers....then the peak of the bellcurve is not -9.
and what i meant before might benifit from visual aid?
This one is IQ, but 100IQ is the peak, equate that to -9.09%, and realte 115IQ to a 0% ROI....there are ~15% of the population above 115IQ
