ROI to ITM Calculation

[AleoMagus]

the 4/9 figure was suggested once as an upper maximum. This was debated a bit, but is probably at least close to correct

keep in mind though that this is only a maximum theoretical value

In reality people post very large samples which exceed this, and in reality this is impossible at the high high stakes.

At high stakes, many excellent players are barely over 35%, and they are happy about it.

Just convert the suggested ROI maximums back to ITM% in the opposite manner which you have been, and it should give you some idea of reasonable ITM values. In other words, you are doing it right.
