De-Load and Rotating Exercises

I am following Westside For Skinny Bastards III and am on my 3rd week. Today was my 3rd week of Max Effort Upper Body and I struggled on my lift a little but I managed to get another PR. I am wondering if I need a de-load week next week or if I should change my max effort lift next week. Any suggestions?

Here is what my max effort lift numbers look like:

1st Week: Incline Dumbbell Bench Press - 40 x 5, 60 x 5, 70 x 5, 80 x 5, 85 x 5
2nd Week: Incline Dumbbell Bench Press - 40 x 5, 60 x 5m 75 x 5, 85 x 5, 90 x 2
3rd Week: Incline Dumbbell Bench Press - 50 x 3, 60 x 3, 70 x 3, 80 x 3, 90 x 3, 95 x 0

Should I de-load next week? I managed to set a new PR today by obtaining 3 reps on the 90lb dumbbells (last week I did 2 reps), however I was surprised that I couldn’t even get the 95lbs up. Or should I change up the max effort exercise for next week?

Please note, I was able to get new PR’s every week (including this week) in all of my assistance exercises. Following my max effort lift, I did some towel pullups, cable rows, face pulls, dumbbell shrugs, and hand training…and set PR’s in all of these.

Still trying to figure out if a de-load is necessary or if I just went in a little over my head with trying to lift 95lb dumbbells on my max effort lift today.

You don’t deload in any WS setup… including WS4SB. That is the whole point in rotating exercises. Also, don’t be so concerned with getting a PR in assistance. Focus on the main lfit. Don’t train assistance to failure IMO.
