Good stuff Steve. Strikes to the heart of the "good tiller" question. I reckon for the longest time I assumed full arc of tiller was the "best," heck the only way. Perhaps because at that time I had more failures, too much set, etc.. But once you get to where you can pretty much make a decent bow every time, then it becomes more practical to integrate such choices into a project. We still see many posts asking for tiller critique where the fellar posts his full draw, or partial draw, and doesn't show the width profile, or doesn't give any indiciation as to how or where the bow is taking set, less relevant whether he's going for a 7 gpp 3d bow or a 12 gpp moose killin' bow, or even bow lenght, draw weight or lenght.
