Cash Caliper treats secondary-earnings tables as span measurements: the published residual sits between two jaws—gross platform credit and fees that never appear in the same cell.
When a labor bureau or marketplace report publishes “earnings after fees,” the desk marks the opening between those figures. The metaphor is a spring caliper held against residual cash, not a household budget tool.
Readers should expect citations to the original instrument (survey year, sample, definition of fees). We do not convert a span into advice for next week’s shifts.
