The Spitfire kills overclaims by the Bf 109 pilots is near to be scandalous(And we dont know the number maybe claimed also by the ZG 2). Claimed 22 Spitfires for only one really shot down, is really a confirmation of the "Spitfire Syndrome" by the Luftwaffe. The Messerschmitts pilots see Spitfires also in the soup...The good old Hurricane in silence and few fanfarre accounted for a hugue number of Bf 109 destroyed, including aces like Hptm Horst Tietzen from 5./JG 51.
Curious also claims for Curtiss, and one was by Oblt Helmut Wick, not exactly a rookie.
