ok i know there is a projected win type of formula for major league baseball that is:

runs scored squared divided by runs scored squared plus runs allowed squared. then multiply that number by 162 to get projected wins.

but since you only have to win one catagory in major league baseball (runs) it makes is a kinda easy formula. is there or has anyone thought of developing one for like a typical 5x5 scoring league (R, HR, RBI, SB, AVG:W, SV, K, ERA, WHIP) to figure projected wins?

I would figure that since in the hitting catagories HR influences both R and RBI a higher value would have to be assigned to that rather than to the others. and since SB are rare there would be a lesser influence on those. Then on the pitching side ERA and WHIP have a slight cooralation as well.

Would it even be possible to develop an accurate formula to predict this or am i just talking over my head?
