Hello Denes.
In fact I am sure that 1:3 is usual overclaim rate and 1:2 is low level.
Actually very difficult and almost impossible to compare for example Geman claims and Soviet losses as most loss categories is "not returned" and "write-offs due to weared". Especially last one. 40% losses due to wearance? For examle in 1944 wroted-off many P-39, Spit IX and Bostons due to this reason. Seems in fact the reason is some combat and/or non combat damages when aircraft became non applicable for combat.
USAF has special damage grade when a/c could be used in OTU only or for ground studies. But VVS RRKKA not.
May be you have on hand Jagdwaffe claims (OKL award) amount in the East for 1944 ? Interesting to compare.

Best regards.
