Thanks man! 5.4 GB's is huge for most of us (My site is up to 17GB for the month so far..) but NS transfers close to 2TB per month.
So, 5.4/2048 is only .26%. So, based on your number crunching, and what I've read about the monthly bandwidth usage, I would consider this mildly un-important in the realm of bandwidth. However, like we both said earlier, this is HUGE for dialup users.
