The definition
A marker on a base rate computed from few prints, warning that the rate rests on thin evidence and should be read with caution.
How the flag is applied
When a company's base rate is computed from few priced prints, the row carries the flag in the dataset itself. The flag is part of the published figure's furniture: wherever such a figure is quoted, the flag travels with it, and the mark is never stripped in reuse.
Why the figure publishes anyway
The flag exists so that thin evidence is marked rather than hidden. A flagged figure is published with the flag beside it — published with the warning, never replaced by it — so the count behind the rate is visible wherever the rate is.
Flagged and unflagged rows follow the same counting method. The flag records the size of the evidence, not a different standard.
What it is not
The flag is not a verdict on the company, and it is not a claim that the figure is wrong. It records that the count beneath the rate is thin.
Nor does the flag single out a company in any other respect. It speaks only about the number of prints the rate rests on.
