 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?

 Hmmm. Suppose you're searching with Acashic Record and the base chance is 50%. 
For the Waste province, the chance to find a site is 70%.
For the Farm, the chance to find 0 sites is 0.6^4 = 13%, so the chance to find 1 or more sites is 87%.
Its more complicated when searching with the individual spells (because the Waste site must have already been searched with some).
I wouldn't have spent any more than 10 seconds working that out, because I seriously doubt we will ever see a complicated auto-search algorithm. The devs prefer to spend time adding cool new content - and that's fine by me.
