So what is it.  First you say rrdtool fetch *always* returns NaN
now you show that isn't true.

Don't shoot the messenger:  You still need to grasp the basics of
rrdtool.  RTFM, the tutorial and the faq site.

One of the questions I didn't keep in the quoted text asked for
something that, IMHO, is explained multiple times in all three
mentioned resources.

Querying "-s 1033456603 -e 1033456603" on a database with "--step 300"
shows that you don't know what you're doing.
