Like you say, during BOB results were down to a lot of things other than the ability of the aircraft, like tactics, altitude and who saw who first. So it would be possible for the Spit to be worse at everything than the 109 and still get the results it did - but I've never seen a WWII account suggeting a 109 could could out-turn a Spit in 1940, and the Hurricane could turn even tighter than the Spit. I understand that the 109 dove better than the Spit, the Spit turned better, while their Speed was similar.
