Not Tong, but with Mr Kelly being an "either it is or it isnt" person, one or even half a dimple over the center line would define aft. It is either black or its white. That is what I think he is like from reading the book and hearing anecdotes about him. Yoda should be able to confirm.

I agree . . . just wondering if "more aft" or "less aft" is more effective. Could be it depends on what is trying to accomplished or corrected.
