Review plans against actual trip and dwell records, not averages alone; match delay causes to temperature profiles.

Raw damage counts hide differences in use. Divide by cycles from the same scope and period, separating event type from discovery time.

Record added labour, waiting and repair per cycle separately from the part price.

Set sampling interval by event risk and decision need; track battery and memory use with device validation.

Calendar age does not show use frequency. Build a local cycle record by plate or group; check the model manual for service limits.

Use completed cycles as the denominator and log search, processing, movement, waiting and rework separately; compare shifts on equal task scope.

Match plate quantity, ID and destination run at line handover; recheck transfers when the sequence changes.

Observe handling steps with the real load; record task time, assistance, correction manoeuvres and events for the same task.

A freezer finishes only as many ready plates a day as its rack positions and freezing time allow. Work the number from GEBHARDT's freezing time and temperature table, not from fleet size.

Count plates at dispatch and return against run, container and model; keep a discrepancy open until plates and records are reconciled.

Monthly energy totals do not show short demand peaks. Match freezer starts and plate loading times to kW records.

Group runs by stop count and review group size, typical results and outliers together.

Calculate cost per completed delivery that meets product requirements using actual cycle inputs.

Align logger time with stop, load and door records; do not attribute the final-stop reading to route duration alone.

Do not diagnose by touch alone; document residue, segregate the plate and assess suspected leaks.

Match the slope-change time to stop and load data; a repeated sequence guides investigation but does not prove cause.
