Wow cool!
To contribute: I made a Commercial Outpost over a water world (with carbon-water-based life!) and got Tourism 1.40, Agriculture 1.00. I don't know if that's the value for all water worlds, or if the mention of life boosted the Tourism.
Then I built a second Commercial Outpost over the water world. It is also Tourism 1.40, Agriculture 1.00 of course. The main Outpost now has two strong links, 1 Agriculture and 1 Tourism, and its totals are now Tourism 2.20, Agriculture 1.40
So the links from the new Outpost were worth .80 Tourism and .40 Agriculture, I guess. The system doesn't have black holes or anything, but the patch notes say Tourism links are boosted by orbiting a water world. And by "On or orbiting a body with organics" but I don't know if that only means organic signals on landables, or if it counts the organics described in (some?) water worlds and gas giants.
...I'm so lost on the basics of how this work...
Why exactly is that Tourism strong link giving .80? I presume that's a 0.40 base, doubled because it's orbiting a water world. If I built a T2 Tourism Installation (Space Bar), would its strong link give 0.80 base doubled to 1.60?
(I'm using this system to test things but I guess it's a decent agriculture exporter for having no landables)
Edit: I'm most interested in sending a bunch of links into a planetary port which will then (I'm reading?) "pass along" those links to an orbiting port! But I am completely lost on what numbers to expect, there, so I'm trying to understand this much simpler scenario first.
