Crafty learns as it plays. So, after many games, the actual play of the engine may be a bit different as it encounters positions or openings it has modified information for. This is very different from a code change and recompile. If you are trying to produce a reproducable experiment, then you don't change the parameters as you go. If you just want a fun contest, then do whatever you want. So, what are the goals? That should determine the conduct during the contest.
