Been thinking on this ^ idea for moment. While I follow your reasoning, I disagree that the TO bearing to fork distance doesn't matter because you can adjust the cable and lever. I agree that you can adjust the cable and levers such that for a given amount of cable travel you will achieve the correct amount of release fork rotation. However the ends of the release fork are swinging an arc, so depending on the angle of interface between the release fork and TO bearing, you will get differing amounts of linear travel at the TO bearing/PP for the same degrees of rotation at the release fork.

I'm not a mathematician, so I can't express the formula for this, but I'm pretty sure it involves PI.
