Answer as saved, from the thread

Why is Line A viscosity drifting up this week?

ModelledWeakest of 3 cited claims

Why this confidence

Method: Each claim carries the label of its evidence; the answer takes the weakest. Uncited numbers are removed before an answer is shown.
Evidence: EV-A-1180, EV-A-1188, EV-A-1191

Viscosity rose 38 mPa·s over the last 9 batches.EV-A-1180Measured
End-of-hold torque rose with it on the same batches.EV-A-1188Measured
A small agitator speed increase would bring it back inside the band.EV-A-1191Modelled

Card, read-onlyAgitator speed 150 to 158 rpmWaiting

agitator: 150 to 158

ModelledViscosity2490 mPa·s90% interval 2430 to 2560

Spec 2380 to 2600 mPa·s (dashed). Driven by End-of-hold torque, Charge mass, Jacket inlet temperature.

Why this confidence

Method: Line model; band only, no single percentage
Model fit: Accepted, four checks passed
Evidence: EV-A-1188, EV-A-1191
