Remember that whatever you put in is converted to a rate (something per second), and regardless of the timing of your updates, all values are normalised and stored as floats. What you've found is that you can make the normalisation near enough a null operation.
You may find Alex's tutorials at http://www.vandenbogaerdt.nl/rrdtool/ useful, especially the one on rates and normalisation.
