Ea's swing mechanic

Where I do feel what you have noted about the swing path is true (hitting the two points). Distance control with the timing and how dispersion works I am not sure works as sold.

I have seen too many shots not result in the expected distances based off the net power reading.

I believe it does "work as sold", but I feel people maybe don't fully realize how many feet/yards are potentially in play, especially from longer distances.

Let's do an example (with just guesses on some distances just to show the math.)

 Say I am 200 yards from the pin.  0 Elevation.  0 wind. Completely flat green.  Tournament speeds.  I am hitting a 7-iron with that just happens to have a max distance of exactly 200 yards.  No height adjustment on the swing.  We are hitting a standard approach.

The dispersion circle of that club I'll estimate to have a radius of about 5 yards (could be less in actuality, but this makes the math easy).  This means that from the center of the circle (the flag), the circle extends in 5 yards (15 feet) in all directions.  That circle does not account for the effects that Wind, Elevation, rollout, or backspin have on the ball.  If we execute a perfect swing on this club under the 0 wind/0 elevation environment, that means the ball will LAND within 15 feet of the pin in ANY direction.  Under most tournament green conditions on this flat green, there is going to be say ~3-5 additional yards (9/15 feet) of rollout with this club.  This means with a perfect shot aimed directly at the pin, if you get bad RNG, you could be up to 30 feet north of the pin after dispersion and roll.  That would be your longest potential putt. If you get good RNG, it goes in the hole.

Now, we all know that it's near impossible to get perfect/perfect.  We now need to MOVE our dispersion circle to account for the imperfect shot.  So let's say you have a slight overswing (.5%) and come through a bit fast (1.9%).  That's 2.4% power.  2.4% of 200 is 4.8 yards, so we need to relocate the center of the dispersion circle 4.8 yards or 14.4 feet North of the Pin.   We then need to move (if your toon is right handed) to the left to account for the fast tempo (slow would move right).   1.9% of 200 is 3.8 yards.  We now need to take the center of that circle and move it 3.8 yards or 11.4 feet to the left.   With this imperfect swing, the ball will land in that same 15 foot dispersion circle that is now located 14.4 feet north and 11.4 feet left of the pin. With good RNG, the pin is still in play, but with BAD rng you could be waaaay out.  After rollout, if you get BAD RNG, you could be putting from as far as 44.4 feet north (14.4+15+ 15) or 26.4 (11.4 + 15) feet left. The max putting distance based on triangulation would be around 51.6 feet for such a shot.
