Given the number of potential prefixes available from the USA I think the 
more useful information would be a list of the most commonly seen prefixes 
(and therefore, the ones to be avoided).

Even better, look at the number of contacts by prefix, rather than the 
number of stations. E.g., if WZ1A, WZ1B, and WZ1C each make 1000 Qs, and 
WZ0O makes 50,000 (assuming these are the only stations operating with
their respective prefixes), you're probably going to do better with a WZ1 
call, despite the other WZ1 activity.
