Verification

Test	A supervisor watches one press on a long job for an hour, with a stopwatch. For 30 cycles (one cycle is one shot of the press, from mold closed to part out), they time the trimming and packing, and the waiting. They also note whether the press beside it runs a long job too.
Cost	About $45: one hour of a supervisor's time. Nothing is bought, and the press keeps running.
Duration	One hour at one press
Confirmed if	Trimming and packing take less than about a third of each cycle. Then one person has time for a second press.
Ruled out if	Trimming and packing take more than half of each cycle. Then one person cannot keep up with two presses, and only changing the gate in the mold can help. Between a third and half, it depends on the press it would pair with, so time that press too.
