I'm glad you see some sense in this JB, it seems to fly over many peoples' heads.
I have viced a bridge to the table, with CB and OB placed in dimples 4-5 feet apart, and placed a cardboard curtain b/w CB and OB (not OB and pocket) and made the shot time after time with all manner of strokes.
I video'd some of it, but had some problems executing without the cue slipping out of the small bridge on some attempts due to having my left hand over my head filming the shot during execution, but I think it demonstrates the stroke myth quite well.

I did a similar video a long time ago that has a similar theme.

I REALLY REALLY REALLY respect people who take the time to take these concepts to the table and record their efforts.
