^^ It really depends on the program your using, but if your deadlifting 300+ on a weekly basis, chances are your cns is going to become fatiqued very quickly. Some people can do it, I cant. When I was running the bill starr 5x5 I switched to every other week for deads, after about 4 or 5 weeks, and my numbers shot up by 10lbs or more every other week.
