I haven't told you everything about Frazier's shenanigans, Drew. I was saving this one for when things got a bit slow here.
Unbeknownst to our firearms expert, SA Robert Frazier, the greatest gift the conspirators gave to ballistics researchers was to supply a rifle with a side mounted scope as the assassination weapon. The beauty of the side mounted scope is that you will always know where your bullet is impacting at the muzzle of the rifle, simply by measuring the lateral distance from the centreline of the scope to the centreline of the rifle barrel. Once you have this number, plus the data of where the bullets are impacting (right or left of the point of aim) at a close target, say, 15 yards or so, you can mathematically deduce how far left or right of the point of aim the bullets will impact at any yardage further down range.
This is the great disadvantage of a side mounted scope, as opposed to a scope mounted directly over the barrel. While the top mounted scope will always be aligned laterally with its barrel, right out to infinity, the side mounted scope makes the bullet begin its journey, on a converging path, at least one inch to the right. This also explains why it is so hard to sight in a side mounted scope, and why I seriously doubt Oswald would have been capable of performing this task.
Let's say the scope was one inch to the left of the barrel and zeroed at 100 yards. This means the bullet path and line of sight will begin one inch apart and cross at 100 yards. The bullets will impact to the right of the line of sight on a converging course up to 100 yards and, after 100 yards, the bullets will impact to the left of the target; impacting progressively further left as the range increases.
I don't know how we're going to measure the distance between scope and barrel on the assassination rifle but I figured you are the guy to ask, Drew. Think you could work your pixellation magic and produce a measurement?

Mr. HILL. The right rear portion of his head was missing. It was lying in the rear seat of the car. His brain was exposed. There was blood and bits of brain all over the entire rear portion of the car. Mrs. Kennedy was completely covered with blood. There was so much blood you could not tell if there had been any other wound or not, except for the one large gaping wound in the right rear portion of the head.
