For a more extreme example look to the A6M2 vs F4F-4. In a one on one the A6M2 utterly dominates the F4F-4, but in a many on many the A6M2s have almost no hope of winning, at least as modeled in AH.
What you fail to understand here is Pilots in aces high know the strengths and weaknesses of the A6m2 and F4F. During Midway I can show you dozens of After Action Reports showing Midway fighter pilots had no clue how to come the A6m. Some report would say it was doing well over 450mph in level flight, others say it climbed to no end, and turned endless circles around F4Fs.
In Aces high we also tend to have an Alt CAP, at 22k you really don't give the A6m much breathing room for one, few years back I did a scenario where there was no alt cap and the Zeros tore up the F4Fs (primarily because of the biggest factor being more skilled pilots were on the Japanese side for once and not flying F4Fs).
If you put 12 Fresh faced 2 weekers up against 12 veteran pilots flying A6m2 the end results is going to be the same period.
During the Battle of Britain English pilots did have some combat under their belt, far different the F4F pilots did at Midway. Also you have to remember the 109E and Spitfire were almost about the same in capabilities, far different then the Zero which out turned, out climbed, and was faster.
