I responded to Tony also. I suggested the following modification: Since it is not uncommon for the operator to fudge the clock by some finite amount to allow time for forgetting to hit the clock or for technical difficulties, I suggest that at the beginning of the match, the two operators simply inform each other of the "fudge" (IE 5 minutes) and that this be enforced for *all* clock updates for that program. IE if we say our fudge is 5 minutes, then each correction must bring the clock back to the real clock - 5 minutes, no exceptions. In the case of Crafty, I have this built in. so that the operator doesn't have to enter a false time, we simply set an operator overhead which Crafty dutifully removes from the clock before calculating target times. But I don't see why we would object if our opponent hasn't done this and wants to "lie" to the program, just so he consistently lies by exactly the same amount for each clock update...
