I think the hands off method it's a piss poor way to figure out if you got the proper anything. It put's many with way too much saddle setback, and they'd have been better off with a cruiser style bike that has a slacker seat tube.
It only really works if you are pedaling with a decent amount of leg muscle to offset the weight of your upper body. The method gives some people the idea that they shouldn't have any weight on their hands at all. And that never was the original proposition of the test.
