Since I have absolutely no clue about including pictures, the geometry added to Sergios Swing pics are in the attached thumbnail. The difficulty I had in attaching this picture is somewhere between fixing a leaky faucet and rubbing two sticks together to start a fire.
If you start at the first picture of the sequence, notice I outlined Sergios Hand Locations on his Backstroke and Downstroke. I had to extrapolate one to finish the pulley.
Anyway, look at the Centers of the Pulleys.
The Pulleys are the same size. If you review Yoda next to Hogan in "The Gallery" their Heads are much more centered over the ball which results in better Straight Line Delivery Path and smaller Pulleys.
Sergio has small pulleys compared to the average Golfer however not as small as Yoda and Hogan. Keep in mind that for each inch the Pulley decreases in diameter, you have an exponential increase in Clubhead Speed and that means Lower Effort Output for equal Clubhead speeds. And that's not all. Yoda and Hogan enter the pulley closer to the pulleys Horizontal Centerline so even if they use the same size pulley as Sergio, they have more delay in Release. So, two properties of the Pulley are Size and Entrance Location.
Also, please notice that Impact Hand Location is not the Lowest Hand Location during the Swing but that the Center of the Lower Pulley is over the Ball. That means Phenomenal CF. Almost zero Clubhead impact deceleration. His Primary Lever becomes a steel rod. Awesome Clubhead Mass. You can write a book on that Issue alone. Consider that the next time you want to play the ball back in your stance.
Lastly; Do you see very much Delayed Release? I don't. It only looks like Delay because his head is so far behind the Ball at Impact.
Lastly Lastly; The centers of Sergios pulleys align with the impact hand location. That has nothing to do with anything. I just thought it made a really nice looking diagram.
Remember the endless belt is a concept to illustrate the differences in the hands moving in a wide circular fashion versus moving in a sharp more linear fashion. As your pictures illustrate the hands don't actually move in a straight line.
Now as for Sergio . . . go to Youtube and watch some of his swings. He stays right on top of the ball. There's not a lot of moving around in his motion of his head relative to a lot of the pros out there. Go to Youtube and watch some swing visions . . . The other thing you'll notice about this motion is there is relatively little axis tilt in comparison to some of the other dudes out there . . . Zach for example. If Sergio had tons of Axis tilt ala Ben Doyle you'd never have heard of him.
We've been here before but watch his swing and look how high his club is off the ground as the hands get in the area of the right and left thigh. This swing is STEEP. Look at Zach's motion that is SWEEPY. Watch the swings and watch the angle of attacks. Sergio has a big shift to a flatter plane but the swing is still STEEP.
Do some comparison work and see what you can figure out about how the motions are different and how the comparitively work.

I beg to differ. The Endless Belt simply demonstrates that a 46” Secondary Lever attached to a smaller pulley will have greater Clubhead Velocity than a 46” Lever attached to a Larger Pulley but that the end of each Secondary Lever ( and this is the important point of the concept ) travels at the same RPM as the Hand it is attached to, so the Concept blends nicely with the Hinge Concept (with which I also agree) and Clubhead Speed and Hand Speed are related but not necessarily cause and effect. Shorter People will have a smaller pulley. Tall people have a larger pulley. You do not get a smaller pulley if you swing shorter clubs. That's why a Driver has Higher Clubhead Speed than a Wedge. That is also why an apparently short person like Hogan Could Hit the Ball as far as a taller person. If you outline the path of the hands for one foot before and one foot after impact of every golfer in the world, then you'll see this relationship. I'm giving you Jewels here.
I’m not beating on Sergio. If you want different results then put up a different sequence. I can't help it if his Stationary Head looks like a Bobber in a Large-mouth Bass fishing competition. I’m sure that he wasn’t posing for this swing (oops, maybe he was) and I’m sure that it was the only sequence of photos taken of him (oops, maybe not). I’m most sure that Sergio has better Swings. As soon as I find one, I’ll use-em.
However, it’s my understanding that this sequence of him Hangs above the Alter you built for him next to your BBQ Grille. So I thought you would enjoy seeing it again.

Whadayamean? Sergio is 5 feet off the ground. How steep can it really be? (That's not a dig on shorter people, please forgive me)
Comparison work? Who? Me? The Illustration Graphics are merely representing a concept which is unfamiliar to you. The Endless Belt Effect. Comparisons would only illustrated differences among Golfers whereas the Sergio Illustration illustrates the samenesses of the mechanics of the concept.

OK bossman . . . I don't have the hots for Sergio. I'm just illustrating two ends of the spectrum. PLEASE go to Youtube and watch the Zach Johnson sequence versus the Sergio sequence. Heck if you want to see the same comparison with a different name watch Boo vs. Zach. Look at the heights of the clubhead off the ground at that point in the swing comparitively.
Stop the video when their hands get right in the middle of the right thigh . . . tell me what you see. AND Boo doesn't have the "thrownaway" look that you so despise either.
Look at all three . . . . .
I'll put somemore sequences up for you . . . I couldn't find one of Zach.
Have you two guys seen Sergio's down the line Driver swing on the SwingPlex feature at the pgatour website. It is very cool...it would be interesting to see your comments....it shows incredible extensor action and his flattening of his swing plane on the downswing.
Alright dude . . . here's what you need to watch a side by side . . .
You can skip to about the 8 minute mark and then you'll see the difference for yourself what I'm talking about . . .
High clubhead vs. sweepy clubhead . . . AND the dude is hitting a shot outta the rough . . .
First, Both Swings are awesome. Thank you for sharing them.
Second, The commentator shouldn't be talking about something he utterly knows nothing about.
Third, What you think you are seeing is not what they are doing.
Tiger's Hip Center is 2" ahead of his ball location and his Head is dead on the Ball at impact.
Zach's Hip center is dead on the Ball at Impact Location and his head is 2" behind the Ball.
Though Zach moved to his left side perfectly, Tiger moves slightly more.
Zach has a very small #3 Accumulator angle. Tiger's is greater. Tiger can do that because he has higher hand speed. It looks like zach is sweeping compared to Tiger. But, he's not. For you, it's just not having enough information availble to analyze the comparison. Now you do. However, you're ten times more knowlegable than that commentator.
They both have a Straight-Line Delivery Path. Tiger's is slightly more vertical. Zach has textbook form. So does Tiger. TGM Textbook (in this video anyway).

Daryl,
You make it sound like #3 works like #2. Is that right? Aren't they always talking about pulley size and hand speed? Pulley is #2, right? And those discussions are always about hitting the ball the same distance----bigger pulley requires faster handspeed to acheive same distance. How does hand speed affect ability to transfer power through #3? If I have a big #3, do I have to swing my arms slow to get it around the corner? Or can I just rotate my left arm faster? Really confusing. Let me know.
I beg to differ. The Endless Belt simply demonstrates that a 46” Secondary Lever attached to a smaller pulley will have greater Clubhead Velocity than a 46” Lever attached to a Larger Pulley but that the end of each Secondary Lever ( and this is the important point of the concept ) travels at the same RPM as the Hand it is attached to, so the Concept blends nicely with the Hinge Concept (with which I also agree) and Clubhead Speed and Hand Speed are related but not necessarily cause and effect.
