To further prove my point (and because I am an anal retentive dick with nothing better to do) I ran 2 more tests. In both tests I had 200 German bombers executing Naval Patrol missions in the sea North of Normandy which flew a total of about 1300 sorties. In the first test I did not fly any Air Superiority Missions. In the second test I used just about every FB-F in England in the summer of 1944 to fly approximately 4300 Air Superiority sorties over the same area as the German bombers. The two maps below show the Naval Interdiction values for both tests. As you can see there is virtually no difference.
On the one hand it is surprising that no one noticed this until now. On the other hand it is perhaps not surprising as few people play the style of game that Liquid Sky plays. Also, it has only been relatively recently that players were given the option of flying certain air missions in just one air phase (friendly or enemy). Finally, this only proves that Air Superiority missions are ineffective against enemy Naval Patrols flown in the friendly air phase. It could be that AS is effective against enemy Naval Patrols flown in the enemy air phase.
