While we are on the topic of mathematics and sex, I had a sort of "ah ha" moment recently regarding the geometry of the blow job. When one thinks of the standard phallus there is a certain symmetry of cylindrical design assumed but if one reflects on the matter further and ask oneself "Wider or thicker?" it immediately becomes clear (especially if one considers such factors as perceived relative compressibility of tissue) that "wider" is the correct answer. Once one has gained this valuable insight, it suddenly becomes clear why the sidereal approach which may seem like the right one to take fairly frequently is never as comfortable or effective. You will always semi-consciously have to give your neck a little twist and reduce both your range/depth of motion and small muscle control. Therefore, IMO, it is always a good plan to first achieve a position at 6:00 or 12:00 whenever possible. Of course, if you are in a car or some other such situation this advice perhaps can not be heeded but at least a heightened awareness may suggest alternate solutions.
I think you forgot to calculate the posterior size, weight, and cheek depth variable.
