The three 18 WILLIAM SMITH CLOSE sales between September 1996 and February 2021 have been plotted on the graph.

For example, the September 1998 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the February 2021 sale, where it rises to 53% above the HPI.
