The way timing is done on a computer, quantization happens, and you may end up checking the time and being just short, then checking the time again and being over a bit. In the case of Crafty, I try to check the time about 1 time per second for searches > 10 seconds long, about 1 time every 1/10th of a second for shorter searches. That means I can vary by .1 seconds out of 1-2-3 second searches. That is a pretty significant variance and can change the move. at 40/2hr, a second doesn't mean much. at 2 secs/move .1 seconds is a lot.
