Jumping a tooth is probably less likely but I have read that it does happen. As you know, the motors use Hall's effect sensors. So....if there wasn't some undesired movement, then why all of the need to resync? Just thinking out loud. So back to my initial question. If the movement is eliminated by a lock, would there be as many sync problems and/or problems with peoples slides going in and out crooked?

The reason to resync the slide's motors is you have a digital comptroller controlling an analog circuit. The side motor's speed is controlled by varying the voltage to the motor. Since it is reasonable to assume the slide's resistance to movement is not linear and uniform side to side, the motors will drift out of sync. This could be eliminated by using a stepper type of motor but you would not be willing to pay the price.
In-flood slides used by Entrgra REDs use a common drive shaft for all gears in the slide's tracks, so the slide is always in sync. This system would require a major chassis modification (raised rail chassis) to the std Ford gas chassis as well as a significant change in the way the in-wall slides are built..
