I don't know the actual calculation, but I can tell you it disproportionately and drastically overvalues the stakes a person plays, relative to their results at their stakes.
For sngs, if a guy has an average BI of $50, and has a -10% ROI (really terrible results), they will still have a higher composite score than somebody with a $10 ABI and a 3% ROI. If both players have an adequate sample, the higher stakes guy should almost never be considered the superior player, unless the games he is playing are insanely reg infested relative to the lower stakes.
I personally just don't give any credence to the ability/100 score. It's not an effective way to compare players of different BIs or different game types. I won't go so far as to call it useless, but if you are a discerning player, you don't really need a composite score to interpret the rest of the numbers anyways.
