quelques précisions :

manpower = sum of all province manpower + HRE manpower (if any)
province manpower = int(125*Units)*baseMP*(%modifiers)
Units = population/200000+0.995 (where pop >= 1000) (capped at 2.0)

In 1453, baseMP ranges from 1 to a maximum of 12 (Moskva) with most provinces being less than 6. (You can see the baseMP as a modifier to the garrison growth rate if you hover the mouse over the garrison size.)

forcelimit = 0.25 * (sum of base tax + workshop and CoT bonuses) * (%modifiers)
(Land and Naval use the same formula; only the modifiers change.)

%modifiers are from policy sliders, national ideas, government type, difficulty level, etc. manpower has a -50% modifier in non-accepted culture provinces. Note that all %modifiers are added together before multiplying by the base (this is true in almost all Paradox game calculations).
