Hi Daryl,-It demonstrated that we could all play with acquired motion-and some of us(me included)probably should try to feel as if we are.:question:

Acquired motion is the description in the book of a swing that goes to the right forearm parallel to the ground position on the back stroke and forward stroke-for most of us "a half swing":)

Strictly speaking, it's not Acquired Motion if you've got a Finish Swivel, so I'd be very surprised if people can still come close to their Total Motion clubhead speed using Acquired Motion.

I can relate to how this works because one day I was messing around with a speed stick and did two swing.

ONe was a full out swing where I got 139
the other was a swing where i put myself in the nine oclock position, held that position for a couple seconds, then fired from there.
and the big difference between the two, 4 mph

But did you stop at Follow Through (both arms straight), or did you go all the way to the Finish with the Finish Swivel?

Good point!we went to both arms straight ,right arm parallel to the ground but I am sure we(swingers)all added some pivot so Iguess it was a half swing rather than acquired motion.I apologise for misleading anyone...but it did demonstrate that lots of us swing too hard.Thanks for the correction!:)

I'm always trying to find something wrong (I don't like it either). And I sense something wrong with these conclusions. First, I find it odd that between the few of us on this thread, that we've hit millions of golf balls and hadn't concluded that a half swing or acquired motion swing (whatever) travels almost the same distance as a total motion swing (is my computer broke?). Second, the club head travel distance between acquired motion and total motion can be almost double in some players. Given this increase in acceleration time, I would think that a total motion stroke would travel much farther. On the other hand, I saw VJ.'s swings and MPH results with my own eyes and a 4 iron acquired motion is equivalent to a Total motion 5 iron.

So, maybe we are "jumping to conclusions". I mean that there is other information that we aren't considering. First, The difference between a 4 iron an a 5 iron may be 10-12 yards with a full swing. I wasn't out in the range with a measuring tape so I don't know how far each ball traveled. So we don't have a control sampling. We didn't take 50 full swings with both clubs and 50 acquired motion swings with each club and measure the results. The test I saw compared the club head speed between a 4 and 5 iron using acquired and total motion respectively. Secondly, did VJ "put more into" the acquired motion than the total motion? I don't know. Third, maybe "our" collective total motion club head travel distance is not as much as double our acquired motion travel distance.

I would agree that when I think of an acquired motion vs. total motion, that the ball travel distance should be greater than the nearly and only 1% difference in club head speed. But, I've been wrong many times. I do think that there is something to this. I'm just not sure exactly what. I know that when faced with a critical distance shot I'm more comfortable with a full swing because I pretty well know my clubs distances. Maybe I should get to know their Acquired motion distances too?

That would make you a tour quality golfer. :)

Length Of Stroke And Clubhead Speed
 

To a point, Length of Stroke (Acceleration Time) is an important factor in producing Clubhead Speed (2-M-2 #3). However, each of us has a Maximum Handspeed that we are capable of producing. And once we've reached that top speed, that's all we can get, no matter how long our Stroke or how much 'effort' we exert.

Think of the runner in a 100 yard dash. Does it take him 100 yards to reach his top speed? No. And once he has reached that top speed, can he run any faster? No. In fact, the best he can hope to do is to maintain that top speed until he crosses the finish line.

And so it is with the golfer and his Length of Stroke.

Lag Loss - 6-C-2-D
 

Beautiful explanation. And this would be related to 6-C-2-D Lag Loss yes?
