~RPE 8 (2 reps in reserve) · range 10–12 kg

Predicted 8-rep max: 12 kg (12 kg, 80% interval) · e1RM ≈ 16.2 kg

This rep max is what the backtest scores. Working sets sit 2 reps under it.

The trend over the last weeks isn't significantly above flat. Hold the weight and chase clean reps; a deload is suggested if this persists 3 weeks.

Model: linear trend (OLS) on 8 of the completed weeks with sets (method picked by the backtest). The week of 5 Oct is still in progress, so it isn't used yet.
