StG.77 losses in October 1942

[Monaco]

As Iwan Lawrinenko is already working on his next book - see books and magazines section Drei „Falken" der II./JG52 auf der Krim im Luftkampf um die Kertsch-Halbinsel 1943-1944 - and I try to support him a question came to me regarding a combat of 5 VA on 29.10.42 over the Caucasus.

It´s pilots claimed the destruction of 7 Ju.87s in one combat, but also lost 5 LaGG-3, 1 Il-2 and 1 more LaGG severely damaged.
Though the soviet pilots could have done severe over claiming as we have seen in many cases and I found no losses for that day in German data (i.e. in Zeng/Stankeys Dive-bomber and Ground attack units vol.I) Holm´s site shows, that Stab, I. & II./StG.77 lost 1, 4 and 8 Ju.87 through enemy action in October 1942 (= 13 Ju.87).
These units (except 3./StG.77) operated together with from Beloretschenskaja (77 km SE Krasnodar) in the Tuapse direction in October 1942.
In Zeng/Stankeys book I found the following losses: Stab: 1 on 11.10.42, 1 on 12.10.42, 1 on the airfield on 23.10.42, none for I. Gruppe, II. Gruppe: 2 losses on 4.10.42 and 1 on 20.10.42. This would be 6 Ju.87s, but for different parts of StG.77.
Maybe someone can enlighten me...?
