Site Searching Statistics Questions

[sector24]

You'll have to excuse me because I R not guud at math, but I have a few site searching questions.

1) If you use a site searching spell like Haruspex and don't find anything, does it have any effect on the chance of finding a site of another magic path? I would think that not finding a nature site would also eliminate the chance of finding a nature/astral site or nature/anything site as well. So as you eliminate more and more magic paths, the chance of there being a site in the remaining paths gets smaller and smaller. Is this correct?

2) Follow up question. If you search nature 1 and don't find anything, how does that affect your chances of finding a site at nature 2, 3, or 4? Presumably the greatest chance of finding a site is at level 1, but the better sites are rarer. Is this correct as well?
