# tool si.act.record_fit_reading

Records one result of a person's own test: the tactic, the market, the measure, its value, the sample and where it came from: The answer gives the reading as a fact the record keeps.

[figure: Over MCP, si.act.record_fit_reading takes FitReadingInput and returns a card whose body is FitReading.]

The answer gives the reading as a fact the record keeps. The call needs the act grant at the brand rung.
