Is connection_flow sheet showing net trade flow between nodes/countries?

Hello. I wanted to check if the connection_flow sheet in Flextool 3.0 output is showing net trade flow rather than trade flow between 2 nodes.

For example, in the image below, the highlighted trade represents that the net trade (exports minus imports) from Namibia to Angola is 3483953 MWh. Is it correct?

Also, in the group_flows sheet, I understand the flow values for connections is the net value. is that correct?

Yes, they are net flows. The group_flows take the perspective of the nodes that are the members of the group: it sums all flows coming in (positive) and going out (negative) to the member nodes. It also separately reports the losses from the connections between the member nodes.

It should probably be named node_group_flows to make it more clear.
