yea.it does on the time.
i see you are 1800ish, i think 2100 is pretty good. I'm 1800 otb and I've hit 2700 TT before I reset, but that required skipping puzzles i wasn't sure I could solve, and sometimes just taking as long as it took, even if that required getting only 1 point out of it.
does it take into account how long you take to solve the puzzle????
