How is it possible that Phoebetors rating in Tactic treiner was 4000, and then it suddenly droped to 2855? 

No answers? Admins?

Personally, I don't remember Phobetor ever having a 4000 TT rating. I thought it was some free-member that had that rating, not phobetor. 

I never had 4000. I also remember seeing that someone did have some ridiculous rating like 4000 but it wasn't me. Although 2924 is ridiculously high as well ;) :P

:)) Lydia likes to believe that some things are bigger. Just as in life.

Maybe that 4000 rated player was a top GM dropping in to use the facilities every now and again. Or someone using a computer.

I'd tend to believe the second statement. I mean the higher level puzzles have longer time limits (more than enough to set it up on a chess engine). His rating just kept going up and never really seemed to get any wrong, until he settled at 4000 and stopped. 

But really who is he harming but himself if he cheats on TT ?

Or maybe it was a transformer! who had upgraded its self to a super-super-super computer!

For 2 Days in 2010 i had the problem that my tactics trainer rating did not get down after a failure, it only went up after a success. After an error of mine there was no change at all. I did sent the bug-info to the staff and they fixed it

There have been some 4000, i remember, some had 90+% success. Its easy to cheat at TT. Look who is now #1 at TT and look at his live-rating. If you check his live games ... silly

Edit from Aug,2010: The person with 3000++ Rating at Tactics Trainer and ~1000 at Life Blitz is not in the statistics anymore.
