Back to number 2:
500,936 b received
202,607 b sent
This means 3913 kilobits received, 1583 kilobits sent, over a fifteen minute period that consisted of me leveling off of Bathories and actively talking in my guild. Dividing these by 15, I get 260 kilobits received per minute, 105 sent. Dividing those by 60, I get 4kbps received, 1.4ish kbps sent. It may be different when you're actually in Prontera and loading characters by the minute, but it can't be too drastic.
