The optimiser computes the number inside the signed window; the agent explains it. People with the right accept, adjust in band or decline.
Process agent·Line A·Jacket loop·Hold temperature 84 to 86 °C·14:00TrialRunning trial

Raise hold temperature from 84 to 86 °C

Batches held at 86 °C reached target viscosity 6 minutes sooner in the model of the mixer, inside the narrowed band.
