The Dero Refurbished Price Index is a weekly index computed from daily snapshots collected since 16 September 2026: for each tracked model we take the median of offers, then the median of those medians. Changes are published only for models with at least 20 offers and moves beyond 2%, to filter out statistical noise. The 7-day change is computed on a constant basket: only the 128 models present at both dates enter the comparison, so catalog growth is not mistaken for a price increase. A monthly index will be published after 30 days of history.
