Receiving Lower Level Persian Positions
There seems to be a general rule that the lowest level persian positions you can get when new positions are given is based on the lowest level you currently have in your Oracle. Possibly this also depends on how long your lowest level has stayed unconquered. I can't figure out much more detail than that.
So, I will ask a specific question. If the lowest level position you haven't won, is 21 (and the highest position is in the triple digits), can you ever get a position below 21 again?
Even more specifically, in that situation, can you ever get positions in the 11-20 range?
