Actually I think that may be useful for others too.

I wonder though if it would make sense to extend that in a form to allow "arbitrary" formula to compute results. This could already be
possible on the incoming data with some pseudo-metrics, but I think this may be too expensive (cpu-wise), but had the advantage
that it could feed into the alerts subsystem.
The second possibility would be to just apply it on graph drawing where the formula applies to the data that would usually be
displayed "as is" .
Here we would have enhanced graphs, that pull the data from the backend as is and then runs the formula on it.

Input on the formula would be the current time slice (index) and the individual datapoints for the group members(*) for a given
time slice, so that it would be also possible to have  val(index) = sum(data at index) - sum(data at index-1)
