<br><font size=2><tt>I recently began creating a fifth graph (Last 3 years)
to go along with the typical MRTG-like four (Last Day, Week, Month, Year).
But, I noticed that the statistics for the new 3 Year graph do not match
the 1 year graph even though there are only about 7 months worth of data,
and you would think they should.</tt></font>
<br>
<br><font size=2><tt>I manually checked the values calculated for the 1
year graph (365 days) and they are correct. Things go a little whacked
when I start the graphs 601 days prior to the present. All statistical
values make a quantum change, and from that point back in time, only the
95th percentile changes, and then at a period of every 40 days. E.g., How
can the MAXIMUM change?</tt></font>
<br>
<br><font size=2><tt>Also note that the 95th percentile seems to take 'nan's
into account even in the 'good' period, whereas the other statistics don't.</tt></font>
<br>
<br><font size=2><tt>These are the results I got for various graphs:</tt></font>
