Acquired vs Total Thoughts and Questions

[Yoda]

More questions or thoughts on the Jeff Hull Vids... (I think they are really good)

If as stated by Yoda, that you can hit a 5 iron from Acquired Motion and a 6 iron from Total Motion and
a. The speed registered by the 5 iron will be higher than the 6 iron (my speed measured the same)
b. The distance of the 5 iron will be further than the 6 iron
c. The difference between Acquired Motion and Total Motion speed will be about 5 mph (Seems like this
would increase for the longer clubs. Realize 5 mph is guessmate I am sure) which at about 2.3 yds/mph
is about 11 yds

1. Does anyone know of any studies done on this concept?

Martee,

The purpose of my comments was to highlight the fact that Length of Stroke is only one factor in Clubhead Power. These concepts are not discussed in TGM except as Power Regulation variables, i.e., Swing Radius (Length of Lever / 2-M-2-2) and Acceleration Time (Length of Stroke / 2-M-2-3). Further, I am not aware of any specific 'controlled' studies on the phenomenon.

My statements reflected my own real-time experience with students. In that regard, think of my remarks as 'conceptual guesstimates' that will definitely vary from student-to-student, but within a tolerance that will always support the original premise. Namely, that a controlled motion with a lower-numbered club will get the job done just as well as a not-so-controlled motion with a higher-numbered club.

Remember, too, that real-world, golfer-generated distance -- not laboratory, machine-generated distance -- is dependent on more than just Clubhead Speed. A Ball hit squarely on the Sweetspot will go further than the one hit off-center, and the more-controlled Stroke makes that precision easier to achieve.

I remember the fun we had at the LBG Academy at Old Waverly Golf Club last Spring. With the entire class looking on, student after student -- and the pros, too! -- proved the point. At least one had even greater Clubhead Speed with Acquired Motion than with Total Motion...with the same club!

The reason?

With his Total Motion, he was well into Throwaway long before he reached the Acquired Motion Top! This earlier Release reduced the Acceleration Rate (Lag Pressure / 2-M-2-1) and increased the Release Interval (Centrifugal Reaction / 2-M-2-4), thus reducing the Surface Speed of the Clubhead into Impact.
