Josh Bryant and many others believe the deadlift needs a great deal if work . In stalled at 585 a few years ago . In my workouts I would hit app one lift at around 450 then one in the 500 + range .
I'm in the app 650 range now , and my workout consisted of a 455, 500 warmups, 590 double , deficit pulls from 2" with 40 lbs of chain on my neck with 480,455,420. Then 455 x 3, 4 sets then the rest of the stuff. That's 19 reps with 75%+ ish.
I'm not a train the muscles deadlift guy.
