There are so many other factors when considering how X plane can defeat Y plane in a duel. On paper X plane is vastly inferior to Y yet while in a duel the superior plane is bested. Sure, piloting "skill" and more so experience will go a long way in dictating who wins, but not always.
Speed, angle of shot, SOP tactics (biggest factor, imo), ACM's, type of weapons used (.30 cal MG's vs 20mm cannons, etc), roll rate, turn rate, turn radius, visibility, acceleration, etc, etc. All it takes is for the inferior plane to get a shot on the better plane and it could be over in a matter of seconds.
The biggest thing to remember is that Aces High allows for the models to be flown and a place for the models to be flown in a virtual word, AND that it is not really representative to the real deal simply due to all the factors not able to be brought to the table in Aces High. If a Hurricane Mk I and a 110C met at 12,000 over the English channel a few things need to be considered right from the get go BEFORE the planes ever engage. A: what is the SOP for each plane? Does the Lufty have direct orders to NOT get in to a turn fight? Does he have orders to keep speeds above 250 TAS? Does the RAF pilot have orders to NOT make more than 2 attack passes? Etc, etc. B: Fuel range? Can either plane stick around and actually duke it out or can they each be on station for 5 mins before they have to RTB? C: What about the speeds in which each plane engages? If the Hurricane Mk I is at 200 TAS (think basic patrol) while the 110C begins the fight co-alt at 300 TAS (he was inbound to an area for a search and destroy mission), the odds are in the favor of the 110C for white awhile, imo. Etc, etc. If I were that Luft pilot I sure as heck wouldn't get slow and low vs any fighter. Speed is my life. And not all engagements ended in a win/loss between the 2 planes.
So arguments like these are a bit moot, really. While the "X vs Y" argument is able to be had while going over the charts, etc, once in the air there are many things that simply cant be modeled nor replicated. Oh, and don't forget that 1 major human factor not able to be modeled: the "life and/or death" variable. In AH we can simply re-up. In the real deal it was a very real danger. If you're in a Hurricane Mk I and you see tracers coming from a 110C's front guns I'd be willing to be the bravado you'd have in Aces High would be non-existent in the real deal.
Few things are absolute. The odds of 2 planes meeting at co-alt with equal E and equally "skilled" pilots are so very slim.
