If you feel so inclined not to trust the data Australian generated feel free to run the test yourself, you should not demand he do the work for you.
Just tested the following:
1v1, Angoville, SU vs OKW. SU using Lend Lease's fuel supply drop.
CheatCommands mod.
OKW starts with 3 flaks as "bunkers", they all fire 18 rounds to the plane before it goes out of its range. Schwerer fires 6 times when put in the middle of the map.
12/31 times were taken down by 3 flaks + schwerer panzer.
5/30 were taken down by 3 flaks (base).
10/30 were taken down by 1 Schwerer HQ.
7/10 were taken down by 1 Schwerer HQ + 1 FHT (2 of those 3 times that didn't, somehow the FHT didn't fire).
Hope this helps.
I still find it stupid that OKW gets AA by sideteching (and thus deny some allies' abilities), specially when they also have AA bunkers.
