The results can vary quite a bit, maybe a variance of ~300 kills and ~100 casualties on your side. One game I ran got just over the 4k mark.
I tried to expand out the kill zone but it was not very successful, maybe not enough planes in the south or I will need to specifically make sure the long range bombers only attack into the interior. Now I am testing the ground war and its interaction with the air war. Its looking like you might need to allocate a few JG Gruppe with a Drop Tank to Air Superiority missions as deep as you can get. That way you can defend against VVS attacks from bases that were missed in the interior. For example, in my test, 2nd PG was attacked north and east of Minsk on T1. I haven't swept up and damaged aircraft with my land forces, so either, it no longer applies or I just cant see it.
