Where it comes from
Every rate is read from the money changer's own published board — 15 chains, 181 branches, 23 cities. Nothing is estimated, and a shop that does not publish its rates is not listed. Rates that fall on the wrong side of the interbank reference are rejected rather than published, because a shop cannot profitably buy above interbank and such a figure is a typo or a parsing error.
The shop history begins the day this site started recording it. It cannot be backfilled: no money changer publishes an archive. The interbank series goes back ten years because central banks do publish theirs.
