When the G10 and K4 entered the skys in 10\44 it was against allied fighters updated with 150 Grade. Not into a pre D-Day sky of 125&130 Grade fighters. Allied command being aware that Germany still had more powerful fighters to introduce over the continent pre D-Day, the upgrade to 150 Grade 11 months before the war ends and 3 months before the emergence of the G10 and K4 makes it an acceptable part of the arms race this game purports to represent.
The K4 met allied fighters burning 150 Grade which made the technological differences far narrower than in our LWMA where the K4 is competing against the same generation of aircraft burning 125 or 130 Grade. Especialy with the way we conduct flight operations in the LWMA most of the time below 15k where it's obvious the 150 Grade turned the K4 into an equal and not an unperked WEP monster.
So why do we have an unperked 10\44 WEP monster flying against it's 1944 Allied rivals down graded in performance by pre 7\44 125, 130 AvGas? The K4 performance in the LWMA especialy on the deck versus the spitXIV on 125 or 130 show cases why the Allies began the move to 150 Grade in 7\44 months before the introduction of the K4.
Or do we need a Post D-Day "Really Late War" arena with only 109G6-14\K4, Fw190A8\D9, Ta152, 262, 163 versus Merlin66 spit, spit14, tempest, P51D, 38J\L, P47D-40\M burning 150 AvGas? And maybe a Meteor for grins and giggels.

So what were the Allies over the ETO doing with all of this 150 Grade fuel for the last 11 months of the war, starting before the introduction of the K4?Sea Level---------------------130 Grade--- 150 Grade
SpitfireIX-------------------- 335 mph----- 358 mph +25 lb
SpitfireXIV------------------ 359 mph------ 366 mph +21 lb
Tempest V------------------- 372 mph------ 386 mph +11 lb
Mustang III (V-1650-3)----- 360 mph------ 390 mph +25 lb
Sea Level------------B4 Grade
