Maybe my model was wrong. Maybe it's not "A Colony station generates a link for every economy from its override, regardless of their values, as T1 links for 0.4, which are then subject to modifiers as normal".
Maybe it's "A Colony station passes along each override factor as a t1 link for 0.4,
unmodified".
My Commercial outposts both started with 1.00 Agriculture and 1.40 Tourism. That would mean 1 Agriculture override factor (Water World) and 2 Tourism override factors (Water World, Geologicals).
Then the secondary outpost passed along 1 agr 2 tourism factors for +0.40 Agriculture, 0.80 Tourism on the primary. Unmodified.
This model wouldn't care whether atmosphere boosts agricultural links or not, as these links wouldn't be subject to it. It also doesn't care that the world is tide locked, it doesn't subtract a link.
Caveat: The "two tourism factors" are still displayed as 1 tourism strong link... but the link display is pretty consolidated already, conflating t1 and t2 links.
(The high tech is a medical station I build later, which provides 0.80+0.40 for being above geologicals
and nothing else, no boost from the mention of life, which is why I abandoned the theory that the life counted like biologicals)
