I don't understand the desire to prioritize searches of provinces with no known sites.

The site placing algorithm, as I understand it is:
roll %chance of site
if yes, determine which site then roll again
if no then exit.

Max of 4 sites, but the point is, if there you know there is one site, the chances of another site are just as good as when you didn't know of any.

I'd much rather search a Waste site (+20%) that already had 3 sites than a farm (-10%) that had none.

Am I missing something?
