Adherence

For trained powerlifters, a Repetitions in Reserve (RIR)-based Rating of Perceived Exertion (RPE) scale accurately gauges intensity across the squat, bench press, and deadlift, with 1RM attempts consistently yielding RPE scores of 9.6–9.7.

If you are an experienced lifter, use the RIR-based RPE scale (1-10) to gauge your sets. At your 1RM, you should consistently report an RPE of 9.6-9.7. This scale allows you to adjust your training load daily based on how you feel, rather than rigidly sticking to a percentage of a 1RM test that may not reflect your current readiness. Combine this with velocity tracking if possible for best results.
