No, I live in the real world. There is no reason to believe that comfort level is constant with distance, or that the comfort level changes with distance at an identical rate with every bike.
This is completely wrong, and Joe Riel did the mathematical proof as well (google is your friend). Getting off the saddle and behind it allows for about .85 gs of deceleration, as opposed to roughly .7 when seated. A very large difference.
Yes, moving back can help braking performance. Moving forward, or, as you claimed, moving upwards, harms braking performance. I will, however, give you the benefit of the doubt, and assume that what you wrote was not exactly what you meant, and that your understanding of bicycle braking is actually consistent with Riel's assertion.
