You're quibbling now. You previously stated that 2 seconds is ONLY about 2 CAR lengths. That image is incorrect with respect to the Croft camera cone. The Tall Stone Monument should be in the Croft Photo per that cone. And the RL Thornton sign WAS extremely close to the Tall Stone Monument. This is why they consistently have moved, removed, and relocated landmarks inside Dealey Plaza. Over time, living eyewitnesses and researchers lose track of what was where, and how these Dealey Plaza landmarks related to each other. We saw this Hocus-Pocus in action when Max Holland moved the JFK Limo location on Elm St. by confusing Tina Towner via missing signage on "The Lost Bullet". I would include Euins too, but I do Not believe he was near the Toni Glover pedestal as he claims.
Here’s the Croft photo:

It appears to me that the bend in the wall in the background is aligned pretty much with Jackie and JFK. And that it is also in the middle area of the photo.
Now, here is the same diagram I submitted before, that you thought was wrong, with some additions for the Croft photo position. I already said that the diagram depicts the limo position close to, but less than, a second after the end of the Towner film segment. That makes the limo position in the diagram already placed close to but slightly less that a car length past the point that it was when the Towner film segment ends. Therefore if we add one more car length we should be getting reasonably close to two car lengths past the position it was when the Towner film segment ends; which I already indicated equals roughly 2-seconds.

The black lines I added indicate the position of the limo, as I described above, and the angle of the Croft photo taken at the proper point in time. Notice that the bend in the wall is aligned with the position where Jackie and JFK would be seated in the limo. These diagrams are only rough estimates. You can quibble if you wish; but please keep in mind that these are only rough estimates.
