One inch of bunch actually uses up a little more than two inches of clothing. Two inches of bunch uses a little more than four inches of clothing.
On edit: I see that Jerry has already posted the graphic. Why have you ignored it? Do you not understand it?
Organ's graphic is ridiculous, as usual. Did you happen to notice that his graphic does not include the location of the rear clothing holes?! Look where the holes are actually located in the coat and shirt, and then look at Organ's silly graphic. The photo in his graphic does not even come close to showing a bunch that would move a hole located 5 inches from the top of the collar to the base of the neck. This isn't even a close call.
Anyone who says Organ's graphic shows a large enough bunch to account for the rear clothing holes is either dissembling or suffering from bad eyesight. Again, go look, actually look, at those holes and see how far down they are from the base of the neck.
I include photos of the JFK rear clothing holes in my article "Where Was President Kennedy's Back Wound?":

And I notice that you and Organ once again ducked Willis 5 and Betzer 3, both of which seem to show the coat virtually flat on JFK's back. One of the few halfway honest WC apologists, Jim Moore, rejects the bunched-clothing theory partly because he acknowledges that Willis 5 and Betzer 3 refute it.
Also, none of you has yet explained how the buttoned, tailor-made shirt could have bunched to any significant degree, especially with JFK sitting back against the seat, not to mention how it could have bunched vertically and horizontally in nearly perfect correspondence with the coat. No thinking person can swallow such fantasy.
And, finally, let it be noted that you guys are simply brushing aside (1) the powerful eyewitness evidence that the back wound had no exit point, (2) the compelling evidence that the shirt slits were not made by a bullet, and (3) the undeniable fact that the nick in the tie knot could not have been made by an exiting bullet because it is not on either edge of the knot. Let's just recap the facts about the shirt slits, shall we?
1. They do not correspond with each other in shape, thickness, or location. Indeed, 1/5 of the slit under the buttonhole extends into the neckband, whereas no part of the other slit does so.
2. The FBI found no metallic traces on the shirt slits, but did find such traces on the rear clothing holes.
3. No fabric was missing from the shirt slits, but fabric was missing from the JFK rear clothing holes and from all of the Connally clothing holes.
4. Even the first FBI lab report on the shirt slits said only that the slits could have been made by a bullet fragment. So, clearly, the FBI experts, before they knew what they were supposed to say, recognized that the slits were not bullet holes.
To any rational, honest person, these facts prove that the shirt slits were not, and could not have been, made by a bullet. But you guys can't admit this because it destroys your theory of the shooting.
