A couple of Trackman questions

[spktho]

In the example above, the more DOWNWARD ANGLE OF ATTACK produces a lower shot.

I got that. I was asking another question thinking about using launch conditions to control distance with irons. May have been a bit too simplistic of a question.

Yes, the first one has higher launch and lower spin. Pretty much certain it has more carry.

That's what I was thinking.

I don't have access to flightscope or trackman, our local golf store had driver testing and had the basics spin rates, launch angle and ball speed
I was using a driver and the loft was 10.5 degrees. Most drives had a launch of 13 degrees. Can I extrapolate the angle of attack as 2.5+ degrees.
Or this too simple?

no

It depends.

On the launch angle.

So the statement is true for most low-to-mid-iron shots. But as you move towards 9 irons and wedges the lower shot carries further.. think thinned wedge!

Remember if your throwing a ball maximum carry for a given speed is when you launch the ball at 45 degrees.

The golf shot optimum launch is quite a bit lower due to backspin.

We're talking launch angles of about 14,15 degrees.

Two shots:

One with a dynamic loft of 20°, 0° path, 0° face, and a 0° level strike...

...the other with a dynamic loft of 20°, 0° path, 0° face, and a 5° downward strike.

Which goes lower????

The downward one....

The D-Plane strikes again....

Unless.....the level strike caused lower then sweetspot contact.
