+10% Manpower recovery: A wasted idea. Almost completely negligible, especially for republics since they tend to have a small manpower pool due to them being minor powers, and thus, draws proportionately less manpower from their provinces compared to their base manpower (10,000) which are not effected by manpower bonuses. This is bad since even if it did work on base manpower, it would still be pretty mediocre.

If you stay tiny, it may not be the best idea in the game, but ...

Its among the most popular modifiers the best players at the office wants... Why? Well, you could view it as 10% more mp, but thats not really true. 10% means that you gain 1 year every 10 years in recovery from major wars.
