3/4 was the (very rough) approximation. We only did that with minutes at first, and then extended it to Win Shares, which was logical because the 3/4 ratio was based on the way ABA teams' WPct's went down when they were absorbed by the NBA (a gross oversimplification, I know). So I'm not sure if it holds for points/rebounds/etc., though. I guess you'd have to look at players who switched leagues and see what effect it had on their rate stats... But then you'd have a huge selection bias problem, because only the good players made the leap to the NBA. It's a mess at that point.

Somewhere, you've used 3/4 of ABA Win Shares, I think, to add to NBA totals. What about equivalent Pts, Minutes, or anything else?
