I thought after doing a number of calculations that I understood the formulas for production and projects. But of course I couldn't stop and kept checking. Oops.
At turn 133 of an immense game as Terrans I have a very new colony, Xaanadis III. The details are shown in the screenshots below; the save file is here:

So I start by setting manufacturing to 100% on the wheel and social to 100%, typical at the very start for a new colony. So, let's figure out the production.
Bonuses: 25% production because approval is 100%. 15% production for Terran productivity. And 20% because a relic in range is being mined. OK. That's a total of 60%.
Pop is 0.9. The colony capital gives a bonus of +4 production. So my base production is 4.9? Well, the below it says it is 7.9. This is actually a 61% increase over 4.9.
Question 1. How do I know which bonuses are applied to base production? I had thought all of these applied only to total production.
Now there is still total production to figure. Assuming 7.9 is correct, and using only the bonuses shown in the production window (below) I have 35% addtional which indeed gives a total production of 10.7.
Question 2. Doesn't this mean that a couple of the bonuses have been applied twice?
Alternative Solution: I have absolutely no clue what is going on.
