Meta-Edge weight calculation

[paulscience]

Hi,

I was working with grouping nodes based on attributes (Group column for the example below). After I grouped the nodes and the meta-edge weight is not summed as expected. The meta-edge between meta node for group A and the expanded group B should have a weight of 300400. However, the meta-edge's weight is 30041. I was wondering how the meta-edge weight calculation is done and if there is a way to sum the weight in the way that's expected? Thanks a lot in advance!
