I am glad to hear they are using ambiguity.  But, what is the size of a typical grid square?  It is certainly bigger than 0.2 miles, so in my opinion, they are using the wrong ambiguity.

Can someone give me the email adddress of who to contact in this regard.?  Isnt a grid square something like 60 miles across?  In that case they should be sending 10 mile ambiguity!
