The goal is not to increase your 1RM (one-rep max), but to enhance your overall performance, specifically your 8RM and 3RM. Therefore, the benchmarks for progress are based on your 8RM and 3RM. The program places more emphasis on squats and bench presses, while deadlifts are performed at a relatively lower intensity, serving more as a supplementary exercise rather than a main lift. As the name "powerbuilding" suggests, don't skip the supplementary exercises; they are highly recommended!
Weeks 1-2 serve as a warm-up phase to recover performance from the previous cycle. Weeks 3-4 focus on significantly boosting performance, and weeks 5-6 are dedicated to setting new personal records.
