Misread Metrics: Payload, Repeatability and Speed

Typical misreadings

Comparing payload at different reaches, treating repeatability as absolute accuracy, and using maximum speed as a stand-in for cycle time.

How to compare properly

Compare at the same reach, posture and payload. Ask for the test standard and temperature conditions behind accuracy figures. Measure cycle time on the complete work step.

When reporting

Keep the qualifying conditions with the number. If conditions are unknown, say so.
