Paul, a question.
"Premium Business Capped is the highest priority on the network, and is unshaped on all protocols. No services are affected by shaping or contention, and business capped customers obtain priority access to the network over all other customers up to the cap you select."
The wording reads to me that if you're a Premium Business Capped user with, say, a 50GB cap on a 10Mb line, that another customer with the same capped account with a 100GB account on a 4Mb line takes priority over yours, even though the only thing the other customer has over you is paying for more data? Would a Premium Business Capped customer on a 40Mb line with a 500GB cap be weighted the same on your network as another user with the uncapped version of the account on a 40Mb line that only consumes slightly less than 500GB in a month?
