For Japan it has only +5 as Armament (Genius) and +2 as Intel. Security one is just Crime Fighter.
But this factor certainly have impact, and bigger than it show by percents.
Another example. In DHF'39 at start I do quick grab of Saarbrucken as France. For germans it produced 87 coal (himmler+hess = + 8.5%), and after occupation - 61 (no resource ministers for French at all). Seems very far from 0.4 fraction, though...

Do same Saarbrucken test in DH modless/ DH light. France get precisely 30 / 75 = 0.4. Fine. So <subj> is just another DHF mess.

Same issue for KR. Probably any other mod with (broken? wad... what?) resource ministers will be affected.
