Total Luftwaffe losses in the East

[Jack Sanders]

Hello,
Has anyone come across any figures for total Luftwaffe combat losses on the Eastern front? I have seen various figures which most of which unfortunately list all losses, not distinguishing between combat and non-combat causes.
The most important figures are below:

2,213 total losses from all causes between 22 June 1941 and 3 January 1942 (Groehler).
1,170 combat losses between January and June 1942 (BC/RS 2).
9,766 total losses from July 1942 to October 1944 (Murray + Groehler).

This leads me to roughly estimate total Luftwaffe combat losses on the Eastern front as 10,000 aircraft. Is this supported by other sources, or am I completely wrong?

The reason I am interested in this is that the Soviet armed forces claimed 50,000 aircraft destroyed in the air during the war, so I would like to know the true Luftwaffe figure by way of comparison and as a way of making some preliminary overclaim calculations.

Regards,
