I think the tilting of spin axis of the ball and the divot been down and out aren't enough for your claim about Homer and the d-plane , from what i have read about the d-plane there is alot more to it than that. Seems a bit of a leap.
I never said Homer came up with the D-plane . . . however in 2-D-0 . . . he clearly says PRACTICALLY right angles to the face . . . didn't give the exact percentage . . . can you?
So he didn't have a video camera . . . a radar machine . . . or a computer . . . he was a lot closer than anybody else . . . was it 100%? Maybe not . . .but pretty dang close . . . and tell your homeeeez to spell my name right . . .
