"there is a statement to the effect that if you haen't established communications with the target race then all collected points are reduced by 80%."
And that may or may not stack with the "not your species" penalty (ESP points halved), and, in a splinter colony like this, the "low population" penalty (multiplied by population/10 million).
OUCH. No wonder this is taking so long... I did manage to get a missile design, with two teams going for a while, but um, yeah... I think I'm done with that for now. It's a nifty idea, and I might try it again if I can manage to "lose" a colony again later when I have a LOT more espionage-capable officers (as the Precursors are bound to have some sweet tech, eh?), but for now... not worth it.
It does seem to work, though, which is kinda cool/exploity.
