if you accquire your data at the sampling interval times then no
re-sampling will happen ...

conside this

* setup an rrd with a step of 300 seconds
  this means it will save data at 0:00, 0:05, 0:10, 0:15, 0:20

* read data from your data-source. You get data at
  0:01 - 1, 0:05 - 33, 0:09 - 2, 0:15 - 8, 0:21 - 0

* what how would you like rrdtool to act ? what data should be
  stored  in the  slots ?
