BTW, this doesn't relate to your problem, but on most UNIX systems,
"uptime" returns load averages as 1, 5, and 15 minute decaying-
exponential values, not 5, 10, and 15.  I was just setting up CPU load
monitoring in Cricket (using RRD) so this happened to be at the
forefront of my mind.

Correct, RRD is almost certainly attempting to interpolate as best it
can, from whenever the data happened to be entered, to the values on
the exact 5 minute intervals.
