Question about the locations from which reviews requests are received

For some time I noticed that there are 3 factors that affect the locations of the requests received for reviewing -
1. The location where you play
2. Your home town location as you choose it in the settings
3. Bonus location
Is it known what is the actual impact of each of these factors ? If I travel a lot and play on different cities at my region, is there any minimum playing time to influence the requests I received and for how long does it last?
I would appreciate some clarifications

Nothing is really known about the Wayfarer system. All I can tell you that your current play area and your hometown are more important than your bonus location.
Your current play area also decided which nominations are in the showcase (propably based on the lvl 7 S2 cell you are in) and which Edits you need to review. When I was in holydays at the north sea close to denmark, I recieved quite a lot of edits from denmark what never happened to me before, even though my bonus location is set close to denmark as well.
Thank you very much for the detailed answer. About when did you stop receiving requests from the new area?
