I can't tell if it's done anything. I use the strokes from the instructions: middle to top (diagonal inward) for 50 strokes, and then bottom to middle (diagonal outward) plus middle to top (diagonal inward) for 50 strokes. That works out to about 10 minutes and then it's on to the next side.
I think the theory is to move the lymph. So you have to clear out the top before you can clear out the bottom.
