Still air in the balloon

The FTSE ended 2007 at 6,456.90. Back in August, I constructed a rough RPI-related graph from 1984 onwards, and to get back to the equivalent of 1984 in real terms, the index would have to drop to around 3,000: at the end of that year the FTSE closed at 1,181.10. We forget how far we've come.
