This is for naval:
18.104.22.168 POLITICAL POINT CHANGES: The victor(s) of a naval combat gains political points and the loser loses them (draws have no political point effects). One political point is gained or lost for each fleet of the defeated major power(s) used in that combat, up to a maximum of +/-3 political points.
All MPs in the victorious stack gain the same amount of PPs: The number of ships in the losing stack (what nationalities is irrelevant). It's the same with corps counters, except each counts as 1/2 PP (round up):
22.214.171.124.1.3 Political Points For Winning/Losing Field Combats: The victor now gains political points and the loser loses them, recorded on the POLITICAL STATUS DISPLAY on the Status Card). Half a political point is gained or lost for each corps of the defeated side (rounding fractions up) used during any round of that combat (this includes corps in outflanking forces that never arrive, but not reinforcing corps that do not arrive) up to a maximum of "+ 3" political points. For this purpose a single corps which begins or reinforces a battle with more than 20 factors in it is treated as 2 corps.
The winners go up the same amount that the losers goes down. The number of corps one committed to combat is irrelevant to both sides. It's the raw number of total corps (or fleets) committed from all MPs in the force. 2 Spanish corps + 2 (small) French corps losing to 3 British corps would cause both France and Spain to lose 2 PP each, and GB would gain 2 PP.
Mind you i didnt play EIA, though i have the boardgame, so got the rules, but im to lazy to try figure it out at this hour.
But how are fractions calulated. Im guessing always rounded up(so 1 pp minimum for winning).
Say a 1-6 nation army fights France.
Fr 2 Corps. Alliance (TU-1,GB-1,PR-1,AU-1,RU-1,SP-1).
If France won he would get 3 pps ? Each MP looses 3.
But if France lost, France would loose 1 pp, and all the "winners" would get 1 pp each.
And dont forget, since fleets are not same size as in EIA(aprox half), you might wanna reduce fleets to ½ pps to.
Round up (says so in the rules you quoted).
In the battle you put forth, assuming no corps had 20 or more factors in it,
If France wins, she gets 3pp and each power in the other army loses 3pp.
If france loses, she loses 1pp and each power in the other gains 1pp.
Remove one of the 6 nations (so, there are five corps), and the results stay exactly the same (due to rounding up).
NOTE: This does not include the gain or loss due to having Napoleon or Nelson in a stack.
At LAST! The greatest campaign board game of all time is finally available for the PC. Can my old heart stand the strain?
