I jumped on my first NLP using weights from when I thought I was "intermediate" and got four weeks before I even needed to add a light day, and another six weeks after that. This was something in the neighborhood of a 100 pound increase after I had concluded I was "not a novice." My 1rm was...maybe 375 when I started this? Hard to say. But I would be very surprised if you didn't make some serious progress, even if it is only a few weeks.
