The West Survey does NOT show three points where JFK was hit. You're probably looking at a Robert Cutler production.
I am not "probably looking at a Robert Cutler production". ( Who's he?)
The late Tom Purvis met with Mr. West, and received copies of all his work.
Most importantly, Mr West, per instructions, surveyed in three locations. The final two were 4 + 65 and 4 + 95.
Also CE 875, the book of photographs, mentions photographs being taken every 25 ft.,
excepting 5+00, as this " was about four feet from impact of third shot".
So, 4+96. Or 4+95. Pretty close. Impact of third shot.
Second impact 4+65.
Just an FYI
