I think you could have gotten a full 3x bodyweight IF, you take 5 steps away from bar, get some inner aggression, just walk up to it n rip it off the floor, don't think. You spent 20 seconds bent into position which can tire out legs and lead to mental buildup.
And the neck! Don't snap it like that man! I cringed at that.
(I wont say much about form because I assume that's a max attempt and form gets sloppy when you're pulling so much weight)
Solid none the less
