I am not completly sure about the program costs-table... e.g. standard programs: Rating 1 - 50 , Rat. 2 - 100 , Rat. 3 - 150 . Okay. So far, so good. But Rating 4 - 400 (4 x 100 )? Or 250 (3 x 50 + (6-4) x 100 )?
And what about upgrades. If I have a Rating 4 Edit program can I pay 100y to get a Rating 5 one? The same for hardware... If my commlink has response 4 and I want to upgrade to response 5, is it 2000y or 4000y? I would say software is upgradeable in that sense, hardware not. But the book is not entirely clear about this...
