What I've stated is very simple....and irrefutable.... Bob's elbow cannot possibly reach as far away from his backbone, as Patty's does. It is a physical impossibility.
No, it isn't a physical impossibility. You're simply mistaken. Patty has perfectly human proportions, as has been demonstrated numerous times by numerous people in numerous ways. The figure's "elbow reach" is well within the range of human physiology, as shown by the Poser7 animation posted in the other Bob H thread -- and so is Bob's.
Here are the numbers, in more detail...
The measurements for Bob are very accurate... since, in addition to being taken on a clear image of Bob, they also happen to match my own measurements. I'm also 6'0" tall....of 'average build'...and fairly broad-shouldered.
Like Bob, my shoulder-joint is located 9" from my backbone, and my upper-arm measures the same length as Bob's.
One key measurement, which agrees with Bob's figure... is that, with my arm held straight out at my side... fully horizontal... my elbow measures a length of 20" from my backbone.
Okay, but that doesn't mean your body proportions are exactly the same as Bob's. Sharing the same height and, in your personal subjective opinion, "build" as Bob, does not lead to an irrefutable conclusion that your limb lengths are precisely the same.
See here:

Height is a result of torso length, hip length, spinal column length and femur length, all of which vary among individuals, even those who share the same height. IOW, even if you and Bob are both 6'0", your limbs, including your arms, are predictably different lengths.
So using your own measurements as an ironclad, "irrefutable" guide to Bob's measurements is your first mistake.
Patty's elbow measures about 21-22" away from her backbone, with her arm swung-out at only a 40-45-degree angle, approximately.
It's not even "maxed-out", horizontally... and it's beyond the length that Bob's elbo w can reach with his arm fully raised up, and fully horizontal.
CONCLUSION: Bob COULD NOT POSSIBLY have been Patty....beyond a shadow of a doubt.
The measurements are unaffected by any potential padding....and the difference in 'elbow reach' is beyond any potential error caused by a "Blur factor".
Please provide the work you did to arrive at a measurement of 21-22 inches between Patty's spinal column and elbow joint. Since there is no agreement among anyone investigating the PG film, even among proponents of the film, as to the height of the figure, there can be no agreement as to what constitutes an inch at any point on the picture plane.
Also, please explain how you determined the location of the spinal column underneath layers of either costume padding, skin, fat and muscle; or fur, skin, fat and muscle. Are you measuring from a central line precisely bisecting the vertebrae? On a film with low resolution of a distantly photographed figure? Even on the large, blown up still frame you're using, to my eye it looks like your line is off from center. How can you be certain that you're not measuring from the attachment point of the trapezius muscle, one to two inches laterally from the center line of the vertebrae?
See pics of the back here, keeping in mind that the trapezius runs parallel with the line of the spinal column and could be distorting your measurements:

The same questions can be asked of your placement of the elbow joint, especially if the figure is wearing a suit that distorts the apparent joints of the arm. Suits of this kind have been described, and pictures presented of them, by AtomicMysteryMonster in numerous PG film-related threads. Your placement of the elbow joint is purely subjective, prone to error and in no way "irrefutable" as you claim.
I'll be doing more work towards confirming these numbers... and posting additional graphics which will show another aspect of the arm/elbows, which further supports my claim...
...That Patty's 'extraordinary upper-torso width' is the result of a skeletal frame which is exceptionally wide, for a 6' tall "human"... rather than the result of an 'average human body', padded-out.
Before moving on to the figure's supposedly inhuman width, you'll need do more work in the area of "elbow reach", because what you've done so far doesn't show a thing beyond that you have an overactive imagination that has so far proven to be immune to logic and rationality.
