Well done!
A new datum has emerged which I suggest goes right into the green bucket.
A video taken at the moment of the first shots being heard shows that the second shot is the one that hits the hydraulic line of the forklift.
It’s right at the end of the video and the camera is panning to the left but we still see the hydraulic fluid spraying out when the third shot is heard.
If you look closely you can even see that puff of smoke when bullet #1 hits the guardrail.
It would be very interesting to know exactly the height of that hit on the hydraulic line. The forklift is about 50 feet back from the bleachers so perspective needs to be taken into account.
The owner of that forklift is Black Diamond Equipment Rentals. It would be interesting to get info from the mechanic that repaired that line. Exactly how high off the ground was that hit?
See the link to the post where the video file is on Google Drive…
Also, a video has emerged from someone who was right in front of Building 6. One screenshot shows a spot of light in the third window from the parking lot. This could be light reflecting off the objective lense of a rifle scope. That window looks dark and the other windows seem to show evidence of reflected light.
A scope would be a few inches higher than the barrel of the rifle. Your estimate of 5.5 feet is pretty darn close.
