Have looked in the errata but found nothing to address this issue :
P.267, SR 5th core : RCC decks Vulcan Liegelord & Proteus Poseidon have identical Device Ratings, Data Processing & Firewall attributes ?
Is this a typo ? If not, why would you spend 2,000 Nuyen more & have a harder threshold of availability ?
Is there something about the Proteus model that is better ?
