It isn't a stupid idea it sounds very good and would help motivate everyone. I would happily post my progress as recently I have just started up my stretching again as I really want to progress with it.
We did have a while back a post similar, that was to show the progress of MikeMartial when he tried Tom Kurz's technique. Click Here
Although I feel that a more up to date version would be a good idea. So I am in. I reckon we should get everyone to post their progress. It would be interesting.
