Argghh, I see the problem now that I try to get the data together.
Sometimes each check reports more often than once per second for some
reason.  It's amazing how trying to explain a problem to someone else
helps find the solution :P

Thanks for the confirmation that it should work the way I thought it

Hi Pamela,
You're right, independent RRD files are independent, and so you should
be able to do what you are describing.
Can you provide any detail at all about how you are updating the files?
