The Claim

Between-day variability in repetition performance significantly affects predictive accuracy assessment, and daily strength normalization reduces this variability while revealing greater underestimation of repetitions to failure compared to using baseline 1RM measurements.

In plain English

When people test how many times they can lift a weight, their performance changes from day to day. This makes it hard to predict their true ability. Using a daily adjustment method helps make the results more consistent and shows that people can actually do more reps than what standard tests suggest.
