In chess, this would be nearly impossible to do. It does help when you get taken out of book, at the same point, repeatedly... That is the reason I implemented it myself. IE if someone plays 1. a3 and 2. h3, everybody will be out of book quickly. Now you can re-play the same game over and over (on a server) and clean the program's clock by doing so. With position learning, it still will vary enough that this won't work very well.
