D-Plane = fancy term meaning 'correct laws of ball flight.' 3JACK Oh!, it's a fancy term now,  , i just thought it was the term used by T.J. in his scientific paper describing the correct ball flight physics, there are no ball flight "laws". |

D-Plane means 'Descriptive Plane' a term coined by Jorgenson. Typically people who tell me that they don't understand D-Plane it's because the term 'Plane' screws them up. They think it's a swing plane thing. Much easier to understand for most people when you just say 'it's the way the golf ball flies.'
I hate the term 'the new ball flight laws' because, to my knowledge, the ball always flew based on the path and face conditions like Jorgenson described for quite some time. So by saying 'D-Plane', it helps distinguish what ball flight laws we are talking about.

I had an opportunity spend the better part of the afternoon with Denny today, and I hope anyone that was even remotely thinking about seeing him will actually do so. I continue to be impressed by him.
