Advanced trainees don't make noticeable gains in a month, but intermediates do. The testing of your 1RM is usually done so that you know what weights to train at for your next cycle. If it's built into the program you are following, you should probably do it. I can't really tell from your post whether you are following some predetermined program or whether you just pieced bits together though. If your program follows a M-F schedule, you could deload on M-Th and test on F. Deloads would be about 5-10% lower than week 3 weights, and you'd cut volume down to about 33-60%.
You could also possibly have an introductory or base loading week following Week 4 to lead you into your new cycle if you are not adequately rested.
I'm not Pendlay though, but I hope that helps until he gets around to replying.
