My mistake. D that is 3 octaves above the open D-string, played on the G string, would indeed be the 31st fret. I stand (or sit, as Nigel would recommend) corrected.
Somehow I lost an octave. And I concur that a two octave (24 fret) board should be roughly 75 percent of the scale length, so the rest of the numbers here make sense.
Cool, that's a huge range. Though it gets pretty sensitive up there... on a good day, if I've been playing a lot, I can do alright up to the 17-19 range, but much beyond that you really have to be dialed in (at least on a 35 - it would be a little more forgiving on a 41).
