	I recently needed to take a look at a program someone wrote here
a few years ago. I don't know RRDs enough to understand whats happening.
The data is collected by MRTG every 5 minutes. The program then does
a RRDs::fetch of "MAX" for the timeframe needed. It pushes the results
into a Statistics::Descriptive::Full . It then takes the 95th% of it.
It does the same thing again, but this time does an RRDs::fetch of the
"AVERAGE", pushes the results and takes the 95th. Then it does :


	for the results.

	Does anyone have a clue why? Shouldn't this just be the 95th of
the MAX? I guess I also still don't understand what the MAX is. I thought
a sample was a sample and thats the end of that. How do you get the
average sample, or the max sample?

		Thanks, Tuc
