During a meeting concerning the disaggregation the question popped up if it would make sense to take instead of the arithmetic mean a p_nom wheighted mean for the efficiency of links. See here: https://github.com/openego/eTraGo/blob/dev/etrago/cluster/networkclustering.py#L275
Nothing too important, just s.th. we can decide on while developing the disaggregation method. Maybe there are other aggregation method which can be rethought as well.
If you have any optinions on this already @ClaraBuettner @CarlosEpia. Feel free to share them.
