Smegma....I agree 100% with your assesment of what they are doing. I also agree that this guy would be better served being on a true transfer billing as long as he thinks his bandwidth is going to remain where it has been for the last two months. I see that over the last year his bandwidth has gone up and down and only he knows what the future is going to hold.

Ray... I can only guess what 95th percentile Monthyl Average is....but if you are asking what a true 95th percentile is then let me see if I can help.....it is kind of hard to explain but I am going to try to make it as simple as possible:
Your server is connected to the internet by a NIC Card (ethernet port). That port can be monitored to see exactly how many megabits per second that is running through it at any given time using a program such as MRTG (there are others but MRTG seems to be an industry standard). The MRTG program calculates a 5 minute average and posts it to a database throughout a whole month, as well as gives you the graphical output that you see above.
So, now the end of the month rolls around and you have 8,640 "plotting points"...meaning there are 8,640 5 minute intervals in a month so you have 8,640 readings.
At this time you simply do a "SORT" to the list of numbers and sort them from the biggest number to the smallest. This will have your largest 5 minute usage for the month at the top and the smallest 5 minute usage at the bottom. (boy I hope this is making sense ;)
Since 5% of 8,640 is 432, you simply take the 433rd plotting point in your sorted list and that is your 95th percentile.
I really hope that I did not confuse you more...
