Well for the Ukr attack I think that battle in itself is favorable to the Russians. 95% of the battles result in clearing Ukraine with 2 fighters left, which is an even trade - that is workable. It’s not overly annoying to Germany, but it’s not killing Russia either. The average is 3 armor left, so if we get unlucky and lose up to 3 armor than expected, it’s still acceptable.
But good luck is pretty awesome. There’s a 33% chance that there will be more than 3 arm left, with a significant 13% chance of seeing 1 inf 1 art 3 arm. Germany’s in a quandary at this point; to attack is to significantly weaken other attacks or burn up valuable tanks, to not attack is to let the Russians get away with murder (3 inf for 3 inf 1 art 1 arm 1 fig). So I guess the only choice is for the Germans to strafe in that case.
1 in 3 games will see Germany with an annoying as hell force in Ukraine, and in those other 2 out of 3, the vast majority is at worst doing an even trade, which is acceptable.
That I think gets luck to work for you - the bad luck isn’t so bad, but the good luck is amazing.
I do however like the point that W. Russia is much less secure than normal. That adds a layer of uncertainty to the Ukraine attack, because even if you succeed there, if you mess up in W. Russia that can deflate you.
Edit: nice point about rolling W. Russia first, Gamer.
