Thanks Arnie.

What I mean by heavy and lighter days is that I will still give it level 10, just if I work out that level 10 on a Sunday afternoon for d/b bench press for example is x lbs heavier than I can do for level 10 on a Thursday at 6.30 am, would that give me an advantage over doing it Sunday 6.30am..... just thinking of the old "heavier weights means bigger muscles" things I've heard.
