Timing
Multiple shots spaced over many seconds is typical of a bolt action rifle.
Accuracy
Yeah sure a triangulation of snipers are going to continually miss their target which was moving relatively slowly down Elm Street, as if! Whereas Oswald who was a little rusty missed his first shot and realistically his second shot can also be classified as a miss because JFK's head must have been the target and then the last shot was too high and almost missed, some professional.
Wounds
Kennedy's neck wound was a straight through and through injury a classic FMJ wound whereas a sniper's bullet would have caused a terrible wound and most probably would have killed Kennedy immediately but Oswald who only had a military weapon left two neat holes. Also the theory that Kennedy's back of neck bullet only went in an inch is not supported by the Xrays and beyond that the physics of a slowed bullet only entering an inch, yet not falling short is illogical.

I agree with your post.
Oswald most likely was aiming at the head the whole time. He was trying to kill, not wound. At more than 200 yards, with the entire torso visible as well as the head, I can see him electing a center torso shot. But not for shots under 100 yards.
In addition, with the angular speeds of about:
1st shot: z153 3.70 degrees per second miss by 60+ inches
2nd shot: z222 1.80 degrees per second miss by 8 inches
3rd shot: z312 0.55 degrees per second miss by 2 inches
It makes sense Oswald would get more accurate with each shot. The shots were all under 100 yards and with the angular speed of the target continuously dropping as the limousine got further down Elm Street, we should expect the shots to get more accurate.
All and all, I think this match one what one might expect of a shooter who was:
** several years past his Marine training (I would guess not such a big deal for
shots under 100 yards shots)
** Not real familiar with his rifle (a possible problem, but he did get in 15, 35, 55, etc. practice shots)
** Several months away from practicing shots with that rifle
** Not trained at hitting moving targets, so perhaps not aware he should wait until the
limousine is further down the street before trying the first shot.
But on the other hand:
** Received Marine training, using iron sights, at targets 200, 300 and 500 yards away.
I find the shooting by Oswald pretty plausible.
Certainly, I would expect a conspiracy to employ shooters who would hit with the first shot. Miss with other shots if they liked, just to make it look like Oswald. But don?t miss with the first and risk Kennedy ducking down or Jackie pulling him down.
