How can golfers ever expect to get better if they don't understand root cause and are being misled by those who claim to understand .... but don't?
Muscle contractions cause forces on the levers of the human body. These forces, being unreacted, result in movement in accordance with Newtons F=MA where A is acceleration or first derivative of velocity. Changing velocity is acceleration and when there is a mass involved creates a force (or vice-versa). When there is no apposing force as in the golf swing we get MOVEMENT.
In dynamics, forces do not always come in pairs... Statics (no motion yes)... Dynamics (motion) NO. For example: there is no force apposing the thrust (FORCE) of a jet or rocket engine. Mass is expelled at velocity causing MOTION... F = (dM/dt * V) = MA.
Only pseudoscientists confuse internal loads with external loads aka the forces that cause movement.
Our bodies having mass are constantly subjected to a force (gravity)... What's the opposite of gravity? Anti-gravity? Only on Star Trek people. Without gravity our muscles atrophy and our bones leach calcium (which BTW creates a problem for long term space travel). Gravity causes a beneficial INTERNAL load (but its not called anti-gravity) on our bones and Muscles... BUT GRAVITY DOESN'T (necessarily) MAKE US MOVE! Get it? On to Golf.
In order for any object to move on a curvilinear path, it must be subjected to an acceleration. There is a name for that acceleration that causes a change in direction: centripetal. When that object on a curvilinear path has mass, a force is involved: CENTRIPETAL FORCE. Only uneducated individuals refer to the internals loads imposed on a structure by centripetal force as CENTRIFUGAL FORCES.....
Educated individuals know that the CENTRIFUGAL force is an imaginary one (a fudge factor) that is only used when non-inertial coordinate systems are being analyzed. Any pseudo-golf scientist that tries to tell you that centrifugal force causes motion or is in any way involved in the golf swing ... is blowing smoke up your .... backside. It takes a lot of gaul for said psuedo-scientist to claim Cambridge University's physicists know not what they speak.... absolutely ludicrous when you think about it....
Centrifugal force is not operant in the golf swing. When you hear mention of centrifugal force with respect to the golf swing know that you're dealing with a posuer and move on. Humor him if his ego demands it but move on for there can be no reasoning with the ignorant.

I doubt you need an instructor bucket. SPC yes... Everyone needs SPC Instructor no. I'm guessing you've got decent mechanics already and an instructor (most instructors) will just try to cram you into his imperfect idea of perfection.
SPC = Statistical Process Control... Exactly where are you losing strokes... Putting? Short Game? Fairway misses? You see? SPC will tell you where your process needs refining. Gotta collect the data and be objective about it but... Once you know exactly where your weakness' are you will be able to do what Jack taught Jack (still the best ever): Fix yourself.
Anybody playing to a +1 and still looking for swing changes is looking to get worse... a lot worse... IMOP.

You're killin' me, no_mind. Please . . . use the cat-o-nine tails www.wikipedia.org/wiki/Cat_o'_nine_tails . . . not the old CF argument.
AAAAAAGGGGHHH!
And that cat-o-nine tails... its to keep the kinetic chain gang in-line right?
Sigh...
I see these funny little diagrams with an arrow labeled CF appearing to cause "release"... Uh.... No... thats not the way... awe nevermind .... resistance is futile

That "funny little" CF force arrow is not random. It is precisely parallel to the left arm (2-K #1 and #3) or in line with it (2-K #2).
Out of curiosity, what is your explanation of the dynamic?
BTW, give it your best shot, because this is going to be an extremely short-lived interaction.
Requires a high school physics level of understanding... peruse at your leisure or don't... It does not matter to me and I won't be offended if you opt out. I'll be back in about a week .... business calls.

Oh, now I get it. Thank God I bumbled through high school and Georgia Tech. That settled, and when you get back next week from "business" . . .
Let's play golf.
I'll take the equally deluded Ted Fort, Jeff Hull and 12 Piece Bucket -- -- against the best ball of you and any three of your referenced Cambridge physicists.
Eighteen holes at Atlanta CC: You guys take carts and play the gals' tees (any gal physicists must play from there, too ).
We'll play the tips and carry our own bags.
The Rules are the Rules: Play by them -- including the ball 'as it lies', no 'gimmes' and count every stroke.
Loser pays all expenses, including green fees, meals, lodging and transportation.
Should be fun.
P.S. For the rest of us: The sound you hear now is no mind scrambling for one or more "referenced physicists" with a scratch handicap, a penchant for the Ladies Tees and looking for a U.S. 'getaway'.
thats not the way... awe nevermind .... resistance is futile
