7 iron !

So 20.3 + 3.8 + 10 degrees foward lean = 7 iron?
I that the correct math?

I'm confused by the math on the left... let me try a Sherlock....

Angle of attack aka "the down?" (Vertical swing path right?)
HSP - horizontal swing path (Negative i.e. Swinging left, so outside in a bit)

Delivered loft 20.7 +down 3.8 = club loft 24.5 degree = 4 or 5 iron?

Not really sure what the point is trying to be made by the above video?

I suppose just that the D plane is a correct concept - but not really news to us Manzella-ites though, we accepted this centuries ago (or something)

It was a 6 iron. I usually deloft my irons about 9-10 degrees. I dont have a ton of forward lean. Where did you come up with ten degrees of deloft without knowing the club?

Though a bit silly to draw line on 2-D video, but is this a coincident?

Are you talking about Kevin or is that your tag line?

Delivered loft is the phrase Trackman uses? Because it isn't the delivered loft that's being calculated. I'd be very surprised if you actually delofted it 9-10 degrees.

TrackMan uses the more accurate term—DYNAMIC LOFT.

The loft on the face when the ball separates.

next!

I bet the clubface could be 2* closed at impact and still line up this way in the stills.

I guessed based on the available data. Trying to learn to think in 3D.....
How many degrees on your 6 iron..? 33?
Whats with the lie board? Is it impact tape for your soul...?

What does that mean?? It was wet out, the divots interfere with the radar.

Sorry, I thought you were fitting or something.
I didnt know about the divots. Maybe that why I had trouble getting numbers a couple of times in soft earth. I learned something right there. thanks.
