Raise hold pressure from 720 to 760 bar

Short shots rose on cavity 2 over the last three shift runs while melt temperature held steady. Higher hold pressure closed the gap in 6 of the 8 best runs.

Raise agitator speed from 150 to 158 rpm

Torque at the end of the hold step is 6% above the grade's best batches, which tracks with high viscosity in the last four batches.

EV-A-1188 EV-A-1191

If stoppedStop keeps 158 rpm for this batch and writes nothing new.
