What is RPE Accuracy?

If your RPE ratings are accurate, every set you do should predict roughly the same E1RM. A set of 5 at RPE 8 and a single at RPE 9 should both point to the same max. When they don't, it means your RPE calibration is off.

The Coefficient of Variation (CV) measures how spread out your E1RM estimates are. A CV under 2% means excellent consistency. Over 6% suggests you need to practice RPE calibration - try the RPE Trainer tool.

Common causes of poor RPE accuracy include: overrating effort on heavy singles, underrating effort on high-rep sets, inconsistent technique, and using RPE on exercises you don't perform frequently.

Frequently Asked Questions

At minimum 3 sets, but 5-10 sets give a much more reliable picture. Ideally, include sets from different rep ranges and RPE values to test your calibration across the full spectrum. A mix of heavy singles and moderate rep work is best.
Most experienced RPE users score a B or C grade (2-6% CV). Only highly experienced lifters with years of autoregulation practice consistently score an A grade. A D or F grade indicates you would benefit significantly from deliberate RPE calibration practice.
This is the most common calibration issue. Lifters tend to overestimate RPE on heavy singles (calling RPE 9 what is really RPE 8) and underestimate on higher reps (calling RPE 8 what is really RPE 9). This creates a systematic bias where heavy sets predict a higher E1RM than lighter sets.
Yes, but keep them from the same week or training block. Your true 1RM changes over time, so comparing sets from months apart will inflate the variation. For the best assessment, use 5-10 sets from a single training week on the same exercise.

RPE accuracy analysis is based on the Tuchscherer RPE chart. Results assume consistent technique across all entered sets. Use the same exercise for best results.
