Yes... I still like 'em 32 years later...
besides removing potential aid markers, is there any use?
The trick is you don't necessarily have to select an untested country. Let's say Pakistan is Fair, you could have 2 sort of "free jihad rolls" to try to bring it to Poor.
And even if you do select an untested country, there is always the 1-in-3 chance it becomes Fair upon testing so it's still worth a try.
