You already know you need to specify the RRAs just once.

means: 12 intervals of 300 seconds form one entry in this RRA.  Keep 24 of

300*12 = 3600 seconds.  This RRA can only be used to display one hour.  That
may be a bit too small.

288*300 = 86400 seconds, which is 24 hours.  Each row will be 24 hours.

288*300*31 = 31 * 24 hours

This RRA will be used when you plot more than one hour.  Each row is 24 hours
so that's the resolution you're going to get.

Uh... you didn't read the tutorial, or you copied the example in a strange way?
