The Governor's position variations between z222 and z224
It seems that in the single bullet can work only if the body of the Governor is at an angle of 20 to 25°.
According to this site, the angle would be 37 degrees: http://www.jfkfiles.com/jfk/html/concl1.htm
I tried to make a personal examination on this. I first analysed frame z223, because frame 222 is not of much help, as we only see the left side of Connally, what makes particularly difficult to assess the position of the Governor.
Have a look at the above image, with horizontal lines marking reference objects that are presumably at an angle of 0° with the limo, and a line marking the shoulders of the Governor.
The measured angle is slightly over 4 degrees. Let's say 4.5 degrees.
According to informations found here, (http://jfkassassination.net/russ/jfkinfo/mccamy.htm), Zapruder was filming the limo at an approximate angle of 20 degrees. There does not appear to be a more accurate figure to be found.
A simple calculation brings me the following result : Connally was at an angle between 18 and 22.5 degrees to the right relative to the limo (whether you calculate on the basis of 4 or 4.5°).
Considering the fact that this is a very rough calculation, base on uncertain data (like the Zapruder vertical angle), I consider that on this point, the SBT is validated for that matter.
Now for z222, it is almost impossible to analyze its position.
I nevertheless made a comparison of z222 and z223 to try to reach a conclusion..
From this rough sketch, it appears that the Governor is turned slightly more to the right side in z222, compared with z223. My estimation of the difference is 3 to 4 degrees. This would mean that the "apparent" angle of the Governor in z222 would be in the range of 7 to 8 degrees, thus, taking into account a 20 degrees angle for Zapruder, an actual angle of 31 to 35 degree.
This examination of the positions of Connally in frames z222 to z224 does not allow us to determine whether the Governor was hit between z222 and z223, or z223 and z224 or to exclude either hypothesis.
This
animation of z222 to z224
will maybe help you in
deciding whether of not the bullet
stroked between z222 and z223. Look at the coat.
