Your game, in the statistics industry, would be termed an out lier, Bean.  Exceptions to the rule are not the way to decide if it works or not.
The only thing that makes it an outlier is the mistakes both of us made. It has nothing to do with statistics, the only thing that was sort of unlucky was you losing 3 figs to 1 bb 1 tran.
And yes, Germany has to follow their normal plan in a KJF.  You followed a normal German plan too.  You didn’t try to set up Operation Sea Lion or pull out some wild and crazy idea.
That’s because I’m exactly like you - I play flexibly. Heavy Pearl + med to Gibraltar is the most flexible it gets, both are excellent preparations for both KGF and KJF. Regardless of KGF or KJF you’re right, I play Germany the same, 1 car + 3-4 rounds of pure infantry.
As for why I can’t get E. Europe hard with KGF it’s because Japan has eaten into all of Russia’s profits.  With no income comes no tanks.  You have to set up a push on Japan, and yes, in MOST games Japan will NOT be taking anything of consequence with their ground forces.
But that doesn’t make any sense. If you delay KJF to round 4, Japan will have eaten Russia’s profits the same as in a KGF.
Obviously, the Allies should make an INTELLIGENT choice after seeing what Japan does.  Do they set up for KJF on round 1 like Mr. Bean did?
It’s funny how you like to say you are a flexible player, then do not realize another one when one slaps you in the face. Heavy Pearl and Gibraltar are my ultimate flexibility in both KGF and KJF. German fleet link is a threat, plus there’s almost no point in going east with the med fleet anymore with how easy it is for the Allies to kill a separated med fleet and retake Africa. And I have maximum airforce with Japan in other battles since I’m not using 3 fig 1 bom in Pearl.
I see that you actually do think I was preparing specifically for KJF, when that is not true at all. I am doing exactly what you think you are doing with the Allies - consolidating forces to use them flexibly. Why do you think otherwise - so you feel better about your strategy? With heavy pearl + gibraltar, I am telling the Allies I am ready for anything they want to try. I am telling them I am not expecting either KGF or KJF. Just because you think so only means that you do not actually understand the moves.
