But if you're taking that from an ordinary MRTG log file, you've got
inaccurate data to calculate from (or data of differing accuracy).  If you
want the 446th highest five-minute sample (95th percentile of 12 samples
per hour times 24 hours per day times 31 days in the month), you need to
do something different, as in archive daily data to a file so it doesn't
get averaged.
