The displayed reputation on per site meta is the same as on the respective parent site. However, out of curiosity, I'd like to see the actual reputation users would have on a meta if it was counted independently. I toyed around with the data explorer (and fruitlessly used its search), but all the extras like rep-cap, answer-accepts and bonuses were too much for my crappy SQL and I don't think there is much point in re-implementing the rep-computation algorithm since it's already there.
So, is there a way to show the theoretical meta-rep of users?
