Comment(by nickm):

 Here are the results I got using the may geoip file currently in
 src/config.

 Looking at relay IPs currently in the microdesc consensus, it seems that

 If I use the June geoip file instead, I get 96% agreement or improvement.

 This doesn't seem to be a fluke; when I choose a large number of IPs
 generated at random, I see about 98% agreement or improvement.

 I'm attaching the script I used to do this test.
