I think most of it is coming from starting to develop neural efficiency in the movement. Some of it too I think, as I mentioned in my log, is that I didn't do as many reps as I could have with 295lbs. Some of it also comes from the programming. With this being the first block of the program (and first block of deadlifts in 2 years) the weights increased every week. I have a deload the rest of this week and then the weights drop back to slightly above the first week of this past block and I start going at it again. So a true increase in the lift will come in about 4 weeks when I go for 325lbs. If I get 7 reps there, then I am definitely getting stronger.
