Soviet victory claims before 22 VI 1941?

[Mirek Wawrzynski]

I wonder how many victories did claim Soviet airmen before 22 VI 1941?

There were several small or big air war:

in Spain 1936-1938: I can estimate at least over 210, or even more victories up to 300?
in Chalchyn-Gol: there were about 650 victories.
in Poland IX 1939: several: about 10-15 victories.
in Winter War 1939-1940: there were about 650 credited victories
in China 1937-1940: maybe 100 or more?
in Rumunia in summer 1940: a few (below 10).

So: Soviet airman could attained about 1500-1700 credited victories before 22 VI 1941.

Any comments to above estimation?
