The score was relatively balanced for both sides in the A2G portion.
In the A2A portion, two factors tipped the score in the Axis favor.
1.) The high number of B-25 kills, significantly increased the Axis kill points.
2.) The Axis were able to get more successful landings.
The only adjustment for Frame 2 will be to increase the number of targets for the Axis to attack (with a corresponding decrease in attack targets for the Allies).
