I think if you have the resources you should add live graphs to the front page that graph the annual inflation rates (bit like the Beeb graph they do with Hali-wide data but obviously going back further) just above where you have the tabular data.
I think it make a much more striking case for how the market is flattening than just the current snapshots... obviously it's lot more work though
You should also graph the transaction data and average price live from the OurProperty database!
