CC setup - number of players

By period3, in Star Wars: Armada Rules Questions

The rules are very confusing as they use the phrase 'number of players' quite often, sometimes with the word 'players' prefixed by Rebel or Imperial, and sometimes not. As a result, I'm never sure if they're talking about the total number of players (rebel players + imperial players), or only the number of players for a faction.

Right now, my confusion is in the paragraph:

"The Rebels can only have a number of bases equal to the number of Rebel players plus one. They can only have a number of outposts equal to twice the number of players ".

Does this bold part mean twice the number of *Rebel* players, or twice the total number of players (Rebels + imperials). We have two rebel players and two imperial players: so is the outpost limit equal to 2*4 = 8 or 2*2 = 4?
