And now for the rest of the cities (I still need to get the US data
though). I've checked all the PPLC (capitals) and PPLA (regional
capitals I think) entries in the geonames database. I've shrunk the
search area down to 0.5 either side of the place, which is probably
still too big.

Top 10
(remember points can be shared between places, so most of these London
boroughs will be sharing a set of points I'd think)
Hertford	UK	37137
Hounslow	UK	36548
Endfield	UK	36545
Enfield	UK	36545
Uxbridge	UK	36177
Ealing	UK	35595
Wembley	UK	35526
Twickenham	UK	35494
Harrow	UK	35162
Kingston	UK	34793
Kingston upon Thames	UK	34793
Mainz	GM	34667
Mayence	GM	34667
Hendon	UK	34424
Hammersmith	UK	34224
Wood Green	UK	33848
Wiesbaden	GM	33783
Islington	UK	33439
City of Westminster	UK	33359
Lambeth	UK	33359

The data is available from

There's lots of work still to do on tidying up the algorithm, but just
wanted to share some of the stats in the mean time.
