Actually, creep tuning is usually done on 2-cam bows, and it is not simply to tune for a form flaw. It assures that the cams are in optimum synchronization when they fire, while the shooter is holding the bow. Timing on a crank board will give false results and the bow will not be in proper time for the shooter. The creep tume is more applicable to a standard 2-cam bow where there are 2 identical cable tracks -- one one each cam, even if the cams or wheels are slightly different shapes. On a hybrid cam, you cam do a modified creep tune proceedure to get the cmas to track the same, although there is only one power cable track. In this case, it is used to optimize the nock travel.
