The test time varied but is really under your control. I chose 1 second per suite position up to 5 seconds for the overnight. The only rationale is to get a reasonable test for multiple mobility bonuses in a reasonable time. The current best is mobility_bonus=30, i.e. 20 moves for white and 15 moves for black in this position would give a bonus of 150 (30*(20-15)) and that is against a pawn value of 1000. The test is not really comprehensive enough yet so the above is just for my program with its pc/sq values and standard positon values and doesn't give more value for the mobility of queen vs. knight, or other similar arrangements. I'll be eager to hear your practical game and testsuite results from mobility experimentation. Stuart
