This is interesting. It's something I'm working on but it's only in the incubation stage. I've plotted 10 COG Orbits from a 48 degree wedge to a 12 degree Driver. I've plotted the Orbits full scale from above, behind, from the front and each from 90 degrees to the Plane. When I overlapped each orbit I noticed that the Orbits cross each other about 5-6" aft and forward of Low Point.

The Red Orbit is the Wedge and the Blue Orbit is the Driver.

The Top set of Orbits depict the ball positioned slightly behind Low-Point and the Bottom set of Orbits depict the ball positioned about 5" aft of Low Point.



The Top Drawing shows that a Driver with 12 degrees of Loft will contact the Ball slightly below the equator and the Wedge with 48 degrees of Loft will contact the ball much farther down. Each club between progressively varies in length and loft. This is how I've always imagined impact contact points to be.

The Bottom drawing is startling because it seems to show that regardless of loft or Club length, the contact point is close to the same for every club.

I've accounted for Angle of Attack, Release Point, Loft and Club Length in the drawings.

What to do now?

The next step for me, is to video 10 swings with each club, average them, and plot the averaged orbits. But, that's going to take a lot of work.

So, before going further with the project, I was wondering if I've overlooked something which would invalidate my orbit plotting. If I have, then it's better to chalk it up as another bungled wild goose chase than to spend a month plotting actual orbits.

So, I'm asking for opinions. There must be something wrong with my plotting. ???

Has anyone seen this before?

Hinge?

Subtracting the downward clubhead vector where appropriate?

Just a guess
