default step size of 300 seconds?

If RRDtool does what it promises, you could set the end time to some time
n*300s, and set the start time to "end-300s". That should give you one
stores rate out of the RRA with each CDP is 1 PDP.

don't know how accurate RRDtool is nowadays but there was a time when
start and/or end times were "massaged" to some other number than one would
expect. When discussed as such, the response was more "don't care" than
"will fix", and that's when I lost my passion.

Different versions had (have?) different problems, so whoever is trying
similar things should be prepared to closely look what *exactly* is
happening, as opposed to how it *should* behave (read: is documented).
