I measured it to be almost 2.5x faster than a K6-2-450. My machine always finds d6 at 1:25 and plays 12....d6 at 1:48 (set for 40/1hour). Perhaps it was accidentally forced to move early? In any case it is strange that Century would even consider such a move. But it's not the only strange move I've seen Century make. Jim
