I wasn't the agressor looking for dogfights, the EIIIs bounced us and I was fighting for my life.
On the second sortie the flight I was in hadn't finish forming up when we were pounced upon. I narrowly avoided air collisions at least 3 times that afternoon.

I don't think 11 kills in one day, 2 sorties, is historically realistic. Easiest way for me to reduce the enemy encounters is to lighten the regional air activity.
