This thread will be used to discuss the Sequential Release and Options related to the Sequential Release.
I would like to extend the disuussion of release on the plane to include a piece on "sequential" release.It would be beneficial to first isolate the #2 and #3 Accumulators to better understand them individually because although the Sequence will be #2 then #3, the time distance from when #2 starts and when #3 Starts can very greatly.
The interpretation held by Most, is that #2 is released with the left hand flat to the plane then teh left hand is swivled into horizontal hinging and #3 (formed by the residual #2) is "rolled" through impact. I BELIEVE THIS TO BE AN IMPROPER INTERPRETATION of HK "sequential release".
I have mentioned this before and had some PM discussion -part Of which I include below.

Not quite- We are not communicating - BUT - we are in pm so please let us get this on the same page because I see it as important.
Experiment: First with the left hand only - Flat left, clubface.
Take your flat-vertical- (cocked if U like, that will not change the clubface geometry at this point)
Go to address- backswing flat left to top- back of hand points across plane line 90 deg and at horizon.
TURN left hand to plane. 4-c-2. hand/clubface is on plane.
No we will come down 2 ways- Both will use 4-c-3 roll.
First -I will call this the BAD way - slow motion swing by sliding your hand flat down the plane, at about waist hight start to uncock the left (that is #2 ) if it was BUT keep your flat hand on plane. now just before impact, look at your hand on plane- You must roll 4-c-3 to vertical for impact. NOTE; the roll 4-c-3 must be almost 90 degrees and it occurs in a very short portion of the swing.
Second- I will call this GOOD way - slow motion swing by sliding the left hand down the plane- But - allow/cause the flat left to roll - 4-c-3 so that it is vertical at hip level. 2 points here. the 4-c-3 roll required was only about 30-35 degrees (on the plaqne to vertical) AND YOU are now in the horizontal hinge with a verticalo club face.
This can let the shaft stay on plane and you can use all the cf U can find- The clubface remans unfer the control of FLAT LEFT HAND.
Any speed, any power, any length, the second experiment repeats. over and over.
I can do experiments eith the right that compliment the left and OBEY HK rules.
This is important.
HK would be proud!

As I believe the sequenced release is realy a "trigonometric" or proportional rate function and is completely on plane- with NO CORNERS or swivels dividing #2 from #3 release
Your thoughts. ?

Originally Posted by HungryBear If the release is trigonometric there may only be an isolation in the rate of release of #2 and #3 ie.I would need to think about that because I think that Acceleration Rate may vary depending on Release Point but I think that maximum Clubhead speed is reached almost immediately. Also, the spacing between #2 and #3 must be a Function of something for the Shaft to remain On Plane.
#2 release K function Sin #2
#3 release X function Cos #3
Releas velocity, on the rim of a circle- #2 starts quickly and does not reach 0 until after impact - #3 starts slowly and does not peak until after impact.

So, the Wedges are Aligned at 90 degrees for the Clubshaft to "Release" while aligning to Both Planes simultaneously, so that the Clubshaft can be moved successfully on the Swing Plane. So,there are three Planes to reconcile.Remember- both accumulators reside in the LEFT hand and act 90 deg. to each other. #2 "vertical" #3 "horizontal" but on an incline plane. at the same time holding t6he proper hinge (horizontal) configuration.
WOW. If we were designing the Golf Stroke from the ground up I think that people would raise some serious issues with the difficulty of that. But actually its really simple. The only difficulty is describing the On-Plane necessities as outlined above.
