I don't think I need an extra rest day. Though the weekend was shorter on rest and longer on going hard (also helped a friend move on Sunday) than usual, it's just Friday's deadlifts, mainly. For example, I feel better and more recovered today, the day after 5x5 squats, than I did yesterday, because of the extra day removed from the DLs. Limit DLs just torch me in a way nothing else does. I should be OK for intensity squats on Friday.
