What the hell is a tenth?

A technician's day is often measured in labor hours attached to completed work, not simply the hours spent inside the building. Those credited units are commonly called flagged hours.

A published labor time may determine how many hours a repair pays. Finish sooner and the credited hours can exceed clock time. Run into corrosion, diagnostics, programming, teardown, or documentation, and the opposite can happen.

Manufacturers assign labor operation codes and time allowances to covered repairs. Those allowances may differ from time associated with comparable customer-pay work.

Same repair. Different time. Structured examples let us measure whether those differences form patterns. No slogans required.
