I had a quick glance through this, and it looks like it sort of addresses this concern already, compared with previous guides, but could maybe still could be a bit clearer, a few edge cases:
What actions in a system, affect the station faction vs system faction when they are different.
Mismatched power play, superpower and factions.
You can make an allied faction angry, if you defend yourself from power play police, even if they attack first.
The 'other' side of a transaction. Especially in things like trades. Things like under/oversupply but still profitable. Likely to be true in colonization for example.

Check and fix
