Your train of thought here is seriously screwy… why would you not trust the producers of the thing you are wanting information on… it makes no sense.
Further, if CCP (the source) and Pyfa (3rd party) aren’t to be trusted, why would you trust this random guy on the forum:
Further to this point, had you bothered to actually read the description you’d know it explicitly states the bonus is for the ‘special case’ that is PI:
“10% bonus to ship planetary commodity hold capacity” unless you somehow don’t think that the stuff you get out of PI = a planetary commodity?
As for everyone else in this thread, please don’t feed the stupid, it’s really bad for the game (see this thread as proof).
