Unless he was looking for specific people in the crowd, this would not have been necessary. The bullet drop for 308 at that range is between 60” and 70”. All he had to do was aim at the far end of the crowd and it would land solidly in the crowd. If his calculations are as complete as someone trained in sniping, then he would have to have trained with someone to learn how to do this. But if the numbers are just rough, then it still doesn’t mean much. We already know he was calculating and on a mission. He only needed rough skills to do great damage.
It’s not like bump stocks are designed for accurate shooting. All he was really doing was using the rifle like a hose.

Perhaps he was calculating to a specific spot where an accomplice was supposed to have the car with the tannerite parked. Maybe near the fuel storage tanks.
At that elevation the drop would be minimal, much less than fired at horizontal.
My take also. That old ladder against the wall the we learned in school. And he WAS an experienced shooter.
Why didn’t he book a suite on a lower level such as 12-20.
Throw in a few tracers and he’d have been set. Still, it was fish in the barrel. No rocket science.
I’m guessing it was actually his gambling system.
70 inches at 400 yards??? What do load with, 50% corn starch???
