You need to demonstrate that your proposed MB trajectory was even possible before you can make ANY assertions and your graphics are a non-starter.
If you had been following, you would know it's not a "Magic Bullet" trajectory but a 3D recreation of Z193, to demonstrate where a bullet through Kennedy would end up if fired in the Z190s (which Mason proposed would sail pass Connally on his left side and gently lodge in his left thigh). The model is valid in demonstrating right-to-left issues and thus invalidates Mason's claim.
In my recreation, the bullet does strike Kennedy "high" because the 3D models I use are typically in standard anatomical-position.
Above: Forget Mason's version. It's forever discredited. Regarding Z193 and my reconstruction, compare Kennedy's chin level and left ear relative to his left shoulder. I believe all are much lower than in my anatomical model. As well, to be prefect, the left shoulder (or is it the left shoulder of the jacket) would have to be raised. It's early days and some fine-tuning will be necessary.
The HSCA Photographic Panel noticed that Kennedy in the wounding-position was different from the anatomical-position. Kennedy was slouched forward and the Panel drew the slouch accordingly.
My anatomical-position 3D model would have to have the slouch applied. The slouch would bring more of the back forward and thus the entry point would be lower when the body is returned to the anatomical position.
If one build a 3D model based on surrogates, one would be recreating the surrogate's body type and posture, and not that of the person on the film.
