I am glad you got it. the diagram didn't make any sense to me until i started drawing all over it, then it made sense.
Just took the laser out for a bit and did some practical stuff. Without competition sailing a set course, or instruments it is difficult to get any sort of true data, but I would pinch a bit when the speed came up, until it slowed, went down past polar a bit, picked up tons of speed and pinched again. The final result was that over distance the overall had me pointing higher overall than just sailing polars. I don't know if the VMG was better though... will try it out Monday night at the beer cans.
