On my daily activity stats in tactics trainer I see the following message:
38/60 Correct (57% accuracy) over 35 Minutes Mar 21st, 2013 - Apr 20th, 2013
Assuming that the accuracy is only dependent on solving the problem which I think is the only reasonable way of looking at it if accurarcy is going truly to be different from rating, then this should be a straightforward calculation of Accuracy (%) = 100*38/60 = 63% (2sf)Yet chess.com claims the figure is 57%. Can chess.com do maths?
well i guess they go after correct moves and not correct puzzles.
Correct moves? Unless they are counting moves you don't get to play because you got the puzzle wrong, which would be pretty weird, then the move % would have to be greater than or equal to the correct % no?
@OP: Tactics Trainer takes the time spent into account. If I take very long on a TT problem and pass it, I can earn 20% on it. My stats for the day would then read, "1/1 Correct (20% accuracy)."
You do get some credit for getting the first moves correct but not finding the last move. Not much, mind you, but if it's a puzzle rated higher than you, you can still pick up points. I'm guessing that would be how you could get somewhere between 0 and 100% for a single problem.
OK so it is basically the same as whether or not your rating rises or falls? So what's the point of it?
