Why high-rep WOD sets don't determine your 1RM

A set of 21 deadlifts at 225 lb is real work. It belongs in your history and loaded volume. It does not give PRzilla clean evidence that you can deadlift 383 lb once.

That 383 lb number is what the Epley formula would produce if it were applied mechanically: 225 × (1 + 21 ÷ 30). At high rep counts, the projection gets noisy. Inside a WOD, there is another problem: those 21 reps may have been broken into smaller sets, separated by rest, and performed under fatigue from other movements.

PRzilla keeps that ambiguity out of your 1RM estimate.

Two checks protect the estimate

For standalone strength work, PRzilla can estimate a 1RM from successful sets of 1 to 10 reps. Sets above 10 reps are excluded because the projection becomes too sensitive to endurance, pacing, and technique.

Multi-rep WOD blocks are handled more strictly. They do not drive the estimate even when the stored rep count is 10 or fewer. A WOD component often describes the total work in a block, not one uninterrupted set, and the score does not tell PRzilla how much you rested between efforts.

A single performed inside a WOD may count. No projection is needed when one successful rep at 225 lb means exactly 225 lb.

What counts instead

PRzilla separates three related numbers:

• A successful single is direct load evidence. No formula has to project from multiple reps.
• An estimated 1RM converts a standalone set of up to 10 reps with the Epley formula. A 185 lb triple produces about 204 lb, for example.
• Training Max is a practical current estimate used for percentage-based weights in the app.

Training Max looks across your eligible results and adjusts older evidence:

• Results from the last six months keep 100% of their estimated 1RM.
• Results from six to twelve months ago use 90%.
• Results from one to two years ago use 85%.
• Results from two to three years ago use 75%.
• Older results are ignored.

PRzilla takes the strongest adjusted result and rounds it to the nearest 5 lb for plate-friendly loading. It does not automatically choose the newest set if an older, decayed result still provides stronger evidence of your current capability.

The WOD work is not discarded

Excluding a multi-rep WOD block from 1RM inference does not remove it from your workout. It stays in your session history and loaded-volume calculations. It can still show that you handled more total work or sustained a load better than before.

The filter only stops conditioning work from inflating the strength number PRzilla uses when it calculates percentages.

Log the source you want PRzilla to use

If your session has a strength piece before the metcon, log the strength sets as their own lift with the actual load and reps for each set. Log the metcon as the WOD. That gives PRzilla the information it needs without pretending that every prescribed barbell block was one unbroken effort.

For the 2026 Community Cup 26.2, the three scored lifts are 1-rep-max attempts, so the successful singles are direct strength evidence. In the other Community Cup workouts, multi-rep barbell blocks remain workout history rather than becoming accidental maxes. A genuine successful single recorded in one of those workouts can still count as direct strength evidence.

A high-rep WOD set can say plenty about work capacity. It cannot separate max strength from pacing, fatigue, and rest, so PRzilla does not use it to invent a one-rep max.
