What does researching a tech to higher levels do?
It improves some of the properties of the process or item that the tech allows. The values that improve, or change, are highlighted in the information screen. For example, at level 3-1, a bio-factory only produces 15 CP (with 100 environment and no production modifiers). When you research level 3-3, then the bio-factory produces 20 CP. At level 3-5, it produces 25 CP. However, some tech info doesn’t show an item that improves … if it doesn’t show anything, be assured that something does improve, likely something very specific to the tech. For example, increase and decrease planet orbit have a base value of 20, but this isn’t shown in the tech info screen. But as it is researched, it changes from 15 to 17 to 20 to 22 to 25.
