The estimate blends recent sales with the median asking price. Each sale counts less the older it is, and the more recent sales there are, the more they carry: with none it is the asking price, with 5 recent ones half and half. So it moves gradually, never in a jump. Figures resting on fewer than that are marked low confidence. Medians, never averages. In an asking median no shop counts for more than a third (or an equal share, with fewer shops), so one shop’s price list does not decide it. Parts-only and brand-new units are left out.
Kamerastore Certified is Kamerastore’s own published average for units it grades Certified (tested and working), read 2026-10-10. It is their figure, not Kamarvo’s, and is not part of the estimate.
