I am playing a Stalingrad to Berlin scenario game with Stamb. Currently we are on turn 7.
It is modded slightly. We unlocked all units in theater boxes (but house rule restricting sending additional mobile units to the map, only foot troops allowed) and increased morale and national morale on both sides by 10 (and 15 for Italians and Romanians). The intent of that was to make it more difficult for the Axis to collapse too quickly, as often happens in late game war scenarios, as well as to make it more difficult to inflict ridiculously high losses against the Soviets just by doing deliberate attacks (the higher morale makes them more robust and less routy). This also means that fewer troops are required in theater boxes (which was part of the idea, more units allows some more defense in depth, and the WITE2 map size, compared to WITE1, is too large for the number of counters).
Also, on turn 1 of the game, I set the entire Axis army to supply priority 4 and started building depots, since the scenario lacks huge numbers of depots that any player would have built many turns previously in a grand campaign.
So as a result, on turn 4 I had 600k new units arrive on the map:

The Italic horde:

The Magyar horde:

The Wallachian horde:

The Teutonic horde:

In the commander's report filtering by newly arrived units, the total size of the horde was:

About 100k of that was HQs for the units though.
As a result of all this railing around, over the next 2 or so turns, many (though not all, and I was careful how I did it) of my rails were completely and utterly overloaded. Here for example in the Caucasus (and also elsewhere), I used 32,500 rail capacity on the rail lines on railing troops. The number literally does not go higher than that.

So, how did my supply look? Glad you asked:
Turn 4 logistics:

Turn 5 logistics:

Turn 6 logistics:

Turn 7 logistics:

So, my supply has been basically perfect throughout, with nearly all of my units having 130% supply and ammo or so this entire time.
Finally, here is turn 2 logistics (the first Axis turn, so these are the default logistics on the first turn before I was able to change any settings, for a baseline comparison):

That is presumably more what supply is supposed to be like, and what it is for the AI or for novice players who don't know how to use the logistics system.
This excellent supply was also not just a result of having a lot of freight stored up in front line depots, because this is StB, and you start with relatively few depots and relatively little freight, compared to what you would have in a grand campaign. The weather has also been a mix of blizzard and snow this entire time, which supposedly is meant to make logistics more difficult, but in practice has no discernible effect (other than in 1941).
I also have not even bothered to use pulsing or other special techniques that Axis normally needs to use in 1941. I have just been running my logistics the same way as I would for the Soviets, putting priority 4 depots near the front and letting supply priority 4 do its thing.
You might also be wondering, how are my trucks doing through all of this? Excellently, thanks for asking!
Here was turn 6:

And here is turn 7. The weather was blizzard, but since I have now had a few turns to build depots, my repair pool nonetheless has started to go DOWN by nearly a thousand:

And here was the starting situation on turn 2 (first Axis turn):

So at the start of the game, I had a deficit of 31,359 trucks in my units. (297116 - 265757 = 31359)
And over the past few turns, that deficit has gone down to only lacking 24183 trucks in my units. (322501 - 298318 = 24183)
That is also despite doing ridiculous things like Staying in Demyansk, and some of my supply trucks into Demyansk have had to go through literally 5 separate ZOC-ZOC movements.
I am EASILY outproducing my truck losses. Not just by a bit, but by a lot. Over these first 7 turns, I produced 21,160 trucks:

Meanwhile, this whole time, despite putting as much pressure on my logistics system as I possibly could, I have only lost a grand total of 15,593 trucks.

If you are a discerning reader, you may notice that I lost 4,799 trucks this particular, which seems like a lot. Maybe my wanton logistical profligacy is finally coming back to bite me? But alas, no, that is misleading. 63% of those truck losses, or 3061 trucks, were from a single battle in the Stalingrad pocket where I had 3 mobile divisions surrender:

Needless to say I am not going to be having 3 mobile divisions surrendering in every future turn.
So I only lost 1,738 trucks from other sources such as logistics, which is trivial compared to the ~3500 trucks I produce per turn.
Literally there is no reason to not just set everything on supply priority 4 and rail units wildly hither and thither about the map, without concern of any kind for supply or logistics. At least starting in 1942, after the special Axis logistics penalties disappear. After that, the regular logistics system comes into its own (the same one the Soviets have the entire game), and the regular logistics system makes it extremely difficult to have significant supply problems.
