Ok, but comparing with I. and II./JG 54 and III./JG 51 - they had no such problems at all, acting on the very same front sector with the same supply. I don't think TagJagd and Schlacht units were supplied in such a different way.
By the moment I see only an a/c type, F-8 (built on Arado plant in Warnemunde and Dornier plant in Wiesmar), as the reason for this, or it can be an area to speculate/research further.
