ORIGINAL: No idea
Would you say that a 20/18 soviet corps is too overloadad? I thought overloading wasnt linear. I tought the malus was low with few overloading, increasing the more you overloaded. Thus, I tought that 20/18 corps wasnt to bad.
You're right it is not linear - that is just an approximation to make the maths simpler and is close to right for ratings in the middle - it gets more wrong with the extreme ratings (1 or 9 say). EwaldvonKleist, being a good mathematician, gives more exact numbers rather than the cheap and dirty estimate!
The malus is actually disproportionately strong with the first overloading and decreases after that. Basically you can never get to zero, so when you have a lot of overloading a bit more will not make much difference at all. Putting more units into Army Group South at the start of the campaign game is not going to reduce the ratings checks of Runstedt (or only microscopically) - although it is multiplied over many more units. The first does change it more than the second etc.
I do not play a lot as Soviets so I may get my foot in my mouth commenting there. But to my mind 20 for a command capacity of 18 is detrimental. Removing one division (2CP) will give worse ratings for that division, but much better ratings for the other 9 (18CP) - so if the question is ratings checks there is almost no question that you are better off with no command penalties. However the Soviet Union does have many armies that you could move that division to - so they will not lose a whole level of ratings checks. As I tell Axis commanders, a Rumanian general commanding German divisions has better ratings checks than Model does when very overloaded. I am sure the same applies to Zhukov and lesser generals in the Soviet Union.
However there are other reasons than command penalties for your chain of command. For instance it may be necessary to optimise distance to HQ/distance to rail supply chains, make sure all units are in the same command to avoid a battle penalty in a combat, optimise multiple use of the same SUs in an HQ and so on. And also is the point spend best used to remove command penalties. So I would be a bit worried making a blanket statement for Soviet armies.
