Hi there, I'm sure there's something I'm missing, so I hpe that someone
will be able to explain it to me....
In this example taken from Alex's tutorial:

 rrdtool create test.rrd             \
            --start 920804400          \
            DS:speed:COUNTER:600:U:U   \
            RRA:AVERAGE:0.5:1:24       \

Suppose that you want to create a graph using the following command
(still taken from the tutorial):

 rrdtool graph speed.gif                                 \
         --start 920804400 --end 920808000               \
         DEF:myspeed=test.rrd:speed:AVERAGE              \

Which RRA is used??? Because both RRA are defined with AVERAGE. Could
someone explain this to me?
