I have since been under the impression that certain routes have the possibility of finding certain sectors.

Do you remember the route that discovered sector 4? We did 1->3 for the longest time without finding any bamboo or new sectors. I tried 2->3 instead a couple days ago, and sure enough, we found 8 bamboo in sector 2 (OP says 1 can drop it too, but we never got it from 1 - RNG, probably). I was planning to keep doing 2->3, but if you have to do something like 2->1 or 1->2 or 2->3 (all of which are terribly inefficient for us), well, we won't find it that way.
