Here's an interesting "stat" that can be used to describe the strength and breadth of your flag counter's visitor data - the "H-Index" : http://en.wikipedia.org/wiki/H-index

A high H-Index for an FC counter means that not only has your site had a lot of visits, but its had many countries that have each visited a lot of times.  So it is a demonstration of visit strength across many countries.

Imagine. For 25 total visits, we have 5 different FCs scenarios with H-indexes anywhere from 1 to 5.

FC#1
Country 1:  25 visits
H-Index of 1

FC#2
Country 1:  24 visits
Country 2:  1 visit
H-Index of (also) 1

FC#3
Country 1:  23 visits
Country 2:  2 visits
H-Index of 2 (since there are at 2 countries with >= 2 visits)

FC#4
Country 1:  13 visits
Country 2:  12 visits
H-Index of (still) 2

FC#5
Country 1:  5 visits
Country 2:  5 visits
Country 3:  5 visits
Country 4:  5 visits
Country 5:  5 visits
H-Index of 5

Right now, my site has an H-index of 31 (South Africa is ranked 31st, and has had 40 visits). For me to get to 32, I need 3 more visits from Ireland (which now sits ranked at 32, and has had 29 visits).

What's your H-index?
