The Poker table ratings site had what I was looking for, and low and behold, I was 5th in November, an 8th in December, over all players on all sites that are tracked on NL4. But in terms of winrate (BB/100) I'm number 1 by a huge margin (if you exclude the one guy that managed to win $494 in 480 hands; what the hell happened there?).
Note that the site displays BB/100 (big bets) instead of bb/100 (big blinds), so you have to multiply them by 2.
