HB555, the issue is that you can only affect you're single corner of the fight. Maybe you're side won a dogfight it didn't win in real life, but individual pilots can't change the strategic picture.
For example, if a carrier is sunk, there is no reduction in the number of aircraft flown against you in the following frame. And if you win a frame, it doesn't stop the other side from advancing (on the ground, possibly resulting in airfields closer to their strategic targets).
Unless we (the participants) are given control of the strategic situation, it can be difficult to change the outcome of a battle.
