I've found that the only times my deadlift goes up is when I do singles at 90%+ each week. Not many, mind you. But some. All the "under 90%" work doesn't seem to help me.
I've also found good mornings and front squats to be beneficial.
BTW, I prefer to do heavy deadlift singles in waves of 4 weeks. Something like 85, 90, 95, new max. Like I said, if I linger too low, my deadlift suffers.
Good point I forgot to mention on assistance exercises, they should be corespondent to the point where you stall with the bar. Can't budge it of the ground some front squats will help, can't lock it out good mornings and various extension movements will help as well as an assortment of things.
BTB why don't you try deadlifting from 3inch and 6inch rubber mats for a while? You can still do rest pause style. If anything I would do 3 inch deadlifts one week for a one rep max, the next week rest pause deficit deadlifts with around 70% of your max to let your cns recover, the week after try your hand at 6 inch mats, and pound the assistance.
