Luftwaffe fighter losses in Tunisia

[Nash]

Due to that source, the Allies lost 151 aircraft (78 fighters and 73 bombers) in air combat over Tunisia in January 1943. This figure probably is lower than the actual figure, but even this figure gives a relation of five Allied aircraft shot down in air combat for every Luftwaffe fighter shot down in air combat.

Are you sure that the figure of 151 Allied aircraft lost over Tunisia is not all losses, or at least all combat losses, and not just "air - air combat" as you seem to be assuming?
