[wxqc] Wrong focus?

[Philip Gladstone]

I have an experimental version of the site info page that shows some of 
this information:

http://weather.gladstonefamily.net/cgi-bin/wxsite2.pl/c0499

If you look at the neighboring stations area, you get to see the average 
difference between the sensor values. This sometimes can show up some of 
your neighbours.....
