APBRmetrics

I am trying to calculate a "player rater" akin to ESPN's player rater or the rankings described in Dan Rosenbaum's article (http://www.uncg.edu/bae/people/rosenbaum/NBA/fantasy1.htm).

I understand that the formula for the non-percentage categories is:

(playerTotal - leagueAverage) / leagueStandardDeviation

However, for percentage categories, it is a bit murky due to the need to adjust for attempts. I am using:

((player% - average%) / stdev%) * (playerAttempts/leagueAverageAttempts)

Is that correct or is there a more accurate formula?

Thanks for your help,

Eric
