Why? It was the NORM... So you'd perk the 7mms on the C202?
You'd perk the gondolas on any 109?
You'd perk the 30mm option on the 109G-14, when in fact 1/3 to 1/2 of all of them had it?
You'd perk the 6-gun option on the p51D? Well it's got a 4-gun option, right? That must be the standard one, it has less!
90 RPG was the standard for the MGFF when used in 190s. They were dropped for MG121/50s in the A6 and later versions, but those that had the MGFF (A5 and prior) had 90 RPG more than they had 60 RPG.
Take it easy on the "perk that option!" histeria, IK3.
EDIT: Just to be clear, I don't want a 60 rpg option AND a 90 rpg option. I want the 60 rpg corrected to reflect 90 rounds.
