Every rep timed.Reps in reserve, estimated.

Point your phone at the rack. RIRVana times every rep, reads the slowdown, and writes your next set from what actually happened, not from what you guessed on the way to the water fountain.
Follow the same demonstration set from reading to recommendation.

The camera times the concentric of every rep. Solid, full-contrast numbers are things it saw.

Velocity loss maps to a reps-in-reserve range with a stated confidence. Purple numbers are things it inferred.

This set: 310 lbs × 5
310 lbs × 5
Next set: hold the load.
The estimate meets the 2 RIR target.
When the reading says there was room, the next set gets more. When it says you were over, the load holds. One line of why, every time.
Load follows the reading.
Nine weeks of back squat in the demonstration block. The jump is taken only when the estimated effort said there was room, and it waits out the deload. Week four of each wave holds the load and backs the effort off.
Full block, every setLifters who already train close to failure.
The reading earns its keep in the last three reps. If your sets end at 4 RIR, a logger is fine. If they end at a grind and you still write 2 RIR in the notes, this is the instrument you were missing.
