That is because the polling is not related to the storing of the data.
The data is normalized to fit into 5-minute slots in the logfile.

If you're not willing to put some time in it ...

Perminute has nothing to do with the polling interval.  It is related to
the default ``persecond'' (which doesn't exist) in "kb per second".

Straight from the docs:


     Change the default step from 5 * 60 seconds to something else (I have
     not tested this well ...)


   Step[ezwf]: 60

Pay attention to the "not tested" part ...  I have no experience whatsoever
with this option ...   perhaps it will accomplish what you are trying to do.
