Each "theory" in this case is nothing more than a reason to pick any particular planet to begin searching over any other one with no particular reason to believe any one will be more successful than any other one. In other words, rationalizing the pick for a random starting point for a brute force search. Quite literally, based on the actual information we have, it is just as likely to be successful picking any particular planet because it has your favorite number in the name, or because three of the letters in its name are in your sisters' neighbours' ex-husbands first cousin three times removed name...
Nope, you're missing the point here.
Each "hypothesis" starts with noticing a pattern or detail in the site or system we know about and from that
"assumes" this pattern applies to the other sites, using it to
narrow the possible options down to a set which can be checked quickly, allowing the hypothesis to be tested
in a reasonable time and
ruled out so we can move on to another.
The underlying assumption being made here is that Frontier/The Guardians did not place the sites haphazardly and that there is a pattern/detail present in the current site to be discovered which holds true for other sites.
It's not "random" and or post-hoc "rationalization" it's "testing the most likely possibilities first".
Do you have a better method? Given that "sitting on our arses waiting for more clues" or "scanning everything" aren't options anyone here wants to pick.
