DLLP stands for Dynamic Lateral Lane Positioning. I made it up. The name is to contrast with what most cyclists seem to practice: "static lateral lane positioning". In particular, they seem to ride a fixed distance from the edge of the road, no matter what the factors or conditions (with some exceptions of course, but that's the basic description of what they do).
DLLP is simply my take on John Franklin's (author of the book Cyclecraft, see
http://cyclecraft.co.ok) "primary riding position" methodology. He recommends cyclists ride in the center of the lane, unless they have a good reason to temporarily move into the "secondary riding position" (off to the side to allow faster traffic to pass), rather than vice versa.
That's all I have time to explain for now. There is a detailed discussion about it here:
