585 lb Deadlift 

It is! I am pretty conservative when I attempt a new max weight lift personal record (PR). Before attempting a new 1 rep max, I like to set PR's in my 5 rep max, 4 rep max, 3 rep max, and 2 rep max. Once I hit all those numbers, I know I should have the strength to go for the new 1 rep max. I also train specifically for a 1 rep max over the course of several weeks to make sure I am physically and mentally prepared for the lift. There are a lot of considerations that go into it. I never like to attempt a new PR lift unless I am nearly certain I can do it.

You get to 585 deadlift being careless. He knows what he is doing.
