How big is Andoran? (Map scale inconsistencies)

[osuracnaes]

I'm putting together an adventure set in Andoran and I was looking at the map in the Spirit & Liberty player companion. Using the scale, Andoran was about 1,000 miles across. This seemed like a fairly large number, so I compared it against the map in the Inner Sea World Guide. Both the map of the whole region and the small map of Andoran has it at about 500 miles across... big difference. The Campaign Setting also has it at 500 miles.

So Spirit & Liberty is the odd one out, but I was wondering if it trumps the other books since it's specifically about Andoran. Anyone know?

The Inner Sea Guide specifically trumps other sources, particularly ones written before it was published.
