Hi Matt,
Fair comment - i think you're right, my analysis would be on firmer ground if I participated. But.... if I'm correct and this is a fairly powerful form of behaviour modifcation (without informed consent) then I'm also right to be a little bit circumspect. This bike may not have any brakes

By the same logic, I wouldn't go for Scientology counselling, or any number of other things. Thanks for replying.
