In what way is the result not accurate?

When I have calculated volume per second I have not used the 'derivative' funktion and have replaced 'divide(60)' by the 'scale\_interval' function, which can adapt to changing aggregation intervals, as described [in this thread](https://discuss.elastic.co/t/how-to-find-bandwidth-usage-from-netflow-data/62005/8).
