Evidence
Read together, round timers and long-running jobs point to spare cooling time that a short check can confirm.

Cooling timers, large presses
05:12, 06:48, 08:20 and 10:26We read four cooling timers. All were round numbers, which points to a margin added by habit.

Cooling timers, small presses
13:40, 15:05 and 17:22We read three more timers here, all round numbers. The pattern holds across the hall.

How staff set the timers
07:28 to 07:37Plant staff said the timer is "set safe" when a job starts, and left if the parts are good.

Cycle time on one screen
08:24On one screen cooling was 20 of the cycle's 31 seconds. A second saved there shortens the cycle.

Longest-running jobs
Five jobs ran about 18,000 press hours in twelve months. A second per cycle adds up fastest there.

Orders shipped late
About one order in seven shipped late. Orders wait for presses, so freed hours can be filled.
