RSW v0 backtest vs public asking prices.
Real Site Worth publishes calibration because valuation tools should be judged against sourced outcomes. This seed table checks a hand-set RSW v0 backtest range, written after each price was already known, against the public asking price on a cited Flippa broker-directory listing — not a blind prediction and not a confirmed sale. Future rows will use frozen pre-settlement estimates from the Predict the Sale Price loop.
The asking-price column is the public price shown on the cited Flippa broker-directory page, on the date it was observed there — not a confirmed settled sale. The RSW columns are a v0 backtest range, typed in after the price was already known, not a blind prediction made beforehand. A row counts as within range only when the asking price lands between the low and high bound. No uncited prices or vendor-derived values are included.
