Um, no, 37, not 31, unless you think the missing and badly damaged Luftwaffe aircraft were victims of ASB? So 7.78 claimed per loss...and there were also 20-odd Luftwaffe fighters damaged less than 60%, all of which could likely have been claimed. So closer to 5.1 claims per "hit". Meanwhile, the Luftwaffe overclaiming was "only" two-to-one...or maybe 2.87-to-one. Of course, if you count the 17 B-17 surveyed and the 121 damaged but repairable, you get a near perfect record for the Luftwaffe. Except that for the purposes of the air war, the real telltale was the 882 Luftwaffe sorties required to do that damage.
