Working standard
Evidence before estimates.
Every published number carries a definition, a date and a boundary around what it cannot prove.
Read the full method- 01Observe
Record what a source actually shows, with place and time attached.
- 02Normalise
Make dates, prices, geography and property attributes comparable.
- 03Join carefully
Keep possible matches separate until location, imagery or attributes provide enough proof.
- 04Show the gaps
Every result includes its sample size and limitations.
Applied research
