Having been trained under the Derrett handling system I just want to say that I find some of what has been said about that system to be less than accurate. I've never heard the difference between the 2 major systems described as motion vs. position. The way the difference has been described to me is that Mecklenburg uses a lot of pre-cues, while Derrett does not. I'm certain that's an oversimplification.
We use motion or more precisely a change in rate of motion all the time to signal acceleration or deceleration. My dog easily reads that cue whether I'm ahead, behind or lateral from her. Also, no matter what system, or even lack of a system, you are using, you can always allow for opportunities to modify your handling based on what is happening on course -- the 'what ifs'.
It is true that Derrett instructors will quite often tell you to correct your position, most often feet and shoulders, when your dog has gone in a direction you did not intend. But, I don't think I've ever seen a dog handled by Mecklenberg trained handler entirely ignore the foot and shoulder position of the handler. Cuing off the body position of handler is natural for the dog, which is why is very hard to override a body position command with a verbal command.
As we've developed into more of a team, I'm finding that I need to give fewer verbal commands beyond our release word and the occasional use of her name to draw her attention. Saying my dog's name is the strongest verbal cue we have.
I'm not interested in debating whether one system is better than another, because I've seen successful and struggling handlers from both systems. I think the important element in becoming a successful team is consistency from the handler. You can't expect your dog to perfrom consistently when your signals for a behavior are constantly changing.
