RRA's are used for every DS, so you only need to specify them once, like
above.

> RRA:AVERAGE:0.5:1:1200 

That is 600 * 1 * 1200 = 720000 seconds = 200 hours = 8.33 days worth of
high-res data.

> RRA:AVERAGE:0.5:12:24

That is 600 * 12 * 24 = 172800 seconds = 48 hours worth of lower res
data.
It completely overlaps with the first RRA. Is that what you want?

Serge.
