The absurdity of the single-bullet theory can be seen in the fact that the HSCA had to assume JFK was leaning far forward when the magic bullet hit him, in order to make their SBT trajectory work, but this assumption is demonstrably false.
The HSCA didn't say Kennedy's head had to be tilted forward to make the SBT work. They said:
"The best record of Kennedy's posture, torso inclination, and
shoulder "hunching" is a photograph taken by Robert Croft at
about the time of Zapruder frame 161."
"... there is no indication in the Zapruder movie that Kennedy
changed his inclination substantially before he was hit in the
back."
"Thus, it was assumed that, except for turning his head by
about 60° and his torso perhaps by 5°, Kennedy made no major
changes in posture after frame 161."

The Dox drawing with the Kennedy head tilted was to demonstrate how Clyde Snow's "anatomical position" wound track would have to be tilted to reflect the wounding posture for the track. It is demonstrative of that concept only.
The angle to the President from the Sniper's Nest at about Z190 was about 24°, and about 20° for the early-Z220s. The wound track angle on the full drawing (on the left of JFK Exhibit F-46) is about 27°; the downward wound track angles of the drawing on the right are 23° and 6°. The panel said that the missile track would have traveled "downward by 4.0° relative to Kennedy if he were sitting erect (not inclined forward or aft"). The middle silhouette, then, is the closest to how they positioned the wound track prior to adjustments for life changes justified from the Croft photo.
Can you show us where the HSCA said Kennedy's head had to be literally tilted forward some-30° for the SBT to work?
