Ahhh.. you guys ran right by nubs post. It is correct in most applications today that an even tiller would be proper. Even adjustment is preferred, especially with single cam offerings. BUT - there is a method of fine tuning that calls for an uneven number of turns on limb bolts. As previously stated by livbucks, it uses tiller. Not but for some of the most discriminating archers employ tiller tuning, which is better suited for two cam bow shooters. Tiller tuning... ahh, yes, for the Tun-a-holic.
