No, I think you may be correct. I think that maybe I need to specify
RRA:AVERAGE:0.5:1:96        # daily report, 1 point per 15 mins
RRA:AVERAGE:0.5:96:365      # a year's worth of daily averages...right?

i am not sure, in first RRA you have 35040 entry every 900seconds =
3153600seconds, so 525600 minutes, 8760 hours, 365 day

so i think that your second RRA will be never used

but peraphs i have understand anything :)
