cooperative intelligence

[Captain Kwok]

You only get the assigned percentage of points that they are producing, of which any bonus points from cooperative intel are not included. The cooperative points you gain are never seen in-game, but exist only in the intel script that runs during end turn processing.

If both players have cooperative intel to each other at the same amount, then it's a wash and not worth it. The main benefit of cooperative intel is for one party to contribute points to intel attacks via another empire, so that they are not implicated against the target empire.
