The four 20 HARDENHUISH AVENUE sales between November 2002 and November 2018 have been plotted on the graph.

For example, the June 2009 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the November 2018 sale, where it rises to 21% above the HPI.
