What statistics do you look at? if any

Alright, so I have been playing a lot of poker lately, and I have a large hands played sample and I was looking at some of the stats about my play at Bodog. I was wondering if, in the long run you guys look at any particular statistic to judge how you are doing. Here is what I Had.

Hands played: 4326

Hands Won: 23%
Showdowns Won: 56%
Flops Seen: 31%
Win % if Flop Seen: 46%

These are mostly playing SnG tourneys with a few ring games mixed in. My %ROI over this sample is about 60% so its been a pretty good run. Not sure how long I will be able to sustain it.
