you should not set artificial limitations on your abilities. Much of this is in the mind. I have far exceeded what I once thought possible for me. I now realized that there is no benefit to putting any limits on what I may be able to achieve.
As for the question, 585 is a decent amount of weight, but there are many, many on this board that could get to the point where they can do that kind of weight for reps on a number of exercises. Maybe not bench, but squats, deads, rackpulls, RDLs, good mornings, ect.---sure. Many on here can already do that amount and much more.
