That is a 25% boost, not a 50% boost

[anomanderus]

So I took the Quality idea group as my first idea group since I wanted to rapidly reach the land forcelimits modifier it grants

I noticed in the first idea available- the 50% manpower increase- apparently does not work the way I assumed it would

I started with 15,000 manpower and the manpower increase game me about 3,500 manpower or so. That is not a 50% increase, that is more like a 25% increase. I should have over 21,000 manpower if it was a 50% increase.

I'm wondering how it calculates the increase, or if it was changed to +25% but the text was not changed.

Check the tooltip. You probably already had enough modifiers, which add instead of multiplying, that it was effectively about 25%. Or else it's about province vs. other sources of manpower.

it is 50% of base manpower, not +50% effective manpower.

 

[chgrogers]

manpower per year = ( base * ( 1 + from technology ) + flat bonuses) * manpower efficiency

The + 50% is added in the manpower efficiency. They are additive bonuses with other percent bonuses. You already have some bonuses when the +50% is added it appears to be less than it actually is.
