[Xymon] SPLITNCV and graphs

I'm trying to add a new graph to a test using NCV (SPLITNCV actually).  I
read through the graphing tips, I read several emails that provided hints
(not my exact problem but nudged me the right way)...

long story short.   I finally got he graph to show up on my test page...but
the rrd file doesn't seem to be populating the fields as expected when I
run "rrdtool dump".  The only thing I can figure is that the test I'm
performing doesn't run every 5 minutes but every 15 minutes.  Does that
matter?  I would have expected in the worst case that only every 3rd row
would have a value.

What am I missing here?  Note, I dropped my test to run every 5 minutes to
see if this theory is true.

As a side note, it would be extremely helpful if the NCV component didn't
look at the entire status but required a comment block (for example) to
contain it.  That way you could keep your data stream isolated from your
message.  For example:

<!-- NCV data
metric1: 123
metric2: 456
etc
-->

My test kept creating an rrd file for a date string that was part of the
status message.  That's a bit annoying.
