(((PCGDP/10000)-2)^2)/2

per capita GDP divided by 10,000. Minus 2. This means 20,000 = 0 and 180,000 = 16. Square root of that gives you between 0 and 4. 60000 would be 2. Half of that gives you 1.

So the maximum bonus can be gotten at the min inequality of 1 combined with a per capita GDP of at least 60,000. If your GDP is higher you can get away with a little inequality.

What it means "takes half the square root of that" and "That gives a number from 0 to 2, being 1 at 60,000 and 2 at 180,000", I can't imaging such formula.

cool thanks i didnt know how to open the mod manager screen

Ctrl F10 to open the unity mod manager screen. Then just untick the box for this mod and hit save. It will go back to the base game calculation, the result of which shows up in the tooltip when you hover over the pop to show growth.

"It can be toggled live in the mod manager, with no save/load required to see the difference in the pop growth tooltips." how.... i love the idea of this mod though ive wanted a mod like this for a while
