Tactics Trainer Info

Wow, that's great. THANKS!!! I looked up a particular person in the search, but no result came back, despite the fact that this person has a TT rating. What's with that, you think?
Do you know whether anyone has done any analysis of the TT statistics. For example, has anyone figured out what the mean, median, and mode are, or what the ratings constitute the first two standard deviations? I'm asking a lot, I know, but I didn't see any threads on this.

Hmmm... I noticed that search doesn't allow you to view a line graph of their TT rating history.

If you want to find something about a player, ask them
Chess.com does not have a feature that allows you to snoop in to details of other's tactics preformance through time. I think this feature is only available if you want to look at their games statistics. The mean, median and all other ratings and numbers you're looking for are far lower than your level so obv. its something not to worry about. Its worth to mention that alot of players don't bother going through the tactics trainer daily as much as playing games.
I was wondering whether it is possible to find population statistics for th Tactics Trainer, and whether you can view the graphs (etc.) of other players' progress on Tactics Trainer?
