RIR & effort
Track effort,
not just weight and reps.
Reps in reserve records how many more reps you estimate you could have completed with good form. It gives weight and reps the effort context they need.

Two identical loads can mean different things. RIR is how the engine tells them apart.
185 × 6 @ 0 RIR is not the same as 185 × 6 @ 3 RIR.
The first was an all-out effort. The second left an estimated three reps in reserve. With comparable technique, a higher RIR means the set felt further from failure; a lower RIR means it felt closer.
Consistent effort estimates help distinguish a performance trend from the same result ground out under more fatigue. A single RIR estimate is context, not proof of a strength gain.

Record effort with the set.
Record effort per set and compare it with previous performance. Adding reps at a similar effort tells a different story from repeating the same reps closer to failure.
At the top of a prescribed rep range, meeting or exceeding the target RIR supports increasing load. Falling below it means the set was harder than planned and may call for holding or adjusting the target.
Do I have to rate every set?
No. RIR tracking is optional in Settings. Enable it for effort ratings on supported rep-based work, or leave it off if you want to focus on weight and reps. A missing rating is not a measured effort.
On a reps-in-reserve-based RPE scale, 2 RIR corresponds roughly to RPE 8, 1 RIR to RPE 9, and 0 RIR to RPE 10. Both are subjective estimates, not sensor readings. Consistency matters more than claiming precision you do not have.
For examples and calibration advice, read what RIR means in weight training. You do not need to attempt an unsafe extra rep to rate a set.
