German Attack final CV calculation in Heavy Snow

Post by Wiedrock »

Let's start from scratch.

Now we know the only Leader rolls during combat are these affecting the final CV. We also know that I have managed attacks to get with best leaders/shortest HQ ranges a maximum of ~152% of CV (so Starting CV 100 ended as CV 152 with no lost/hit elements). This properly matches with Joels stated x1.25 which can be applied to each group of Ground Elements twice, which gives 156% CV. For the sake of easing things I always assume hat all Elements pass their checks.

Now there are special rules on top of all of this.
The one that's part of this Thread is the special winter rule set for the Germans. This one supposedly should only affect the defensive CV, it is not mentioning the offensive CV, nor the pre-battle-DISruption Germans suffer during fighting in heavy Snow (btw. all these special rules only are applied in Heavy Snow).
Living Manual 1.27, p.192 wrote:Errata: Undocumented rules
Axis units in heavy snow have their defensive CV modified as follows:
Dec 1941 - /2
Jan 1942 - /1.5
Feb 1942 - /1.33
This is reflected in the CV values shown on the map.
In addition, once in combat, there are admin and land combat rating checks
made. For each failed check, the defence value is modified an additional time.
So a unit in Jan 1942 in heavy snow can have their CV divided by 1.5 up to 3
times if it fails both checks.
Okay, now comes the shocker. 8-) This Thread is not about the defensive CV at all, but about the German attacking CV during Winter, when fighting in Heavy Snow.

What this Thread EXCLUDES is/are:
  • German defenses
  • Hasty Attacks
  • enemy SURRENDER/SHATTERED/extreme ROUTs and all kinds of results leading to tens of thousands of CV or causing the defender to end with 0 or close to 0 final CV.

Observations made.

When testing pre-battle Diruption during Winter 41 I found that somehow the final CV on average seemed to pretty often increase (compared to initial CV) compared to non-Heavy Snow fights.
Further, the usual before stated 155% CV increases were exceeded by different magnitudes (180%, 270% 350% ...). Following 2 Battles with such extreme final CV increases from "live" PvP games (I can provide more).

Additionally to these two I looked through 2 AARs on Discord with players posting lots of combats and in their AARs and I made the same observation. Attacks by Germans before/after Winter 41 (Dec,Jan,Feb) and Battles not in Heavy Snow during this three months will never show such increases in CV.

So something seems off. Would be nice if this could be investigated.

I will continue the post with lots of guesswork, for the sake of your brain health I suggest to not keep reading!!!



CONTINUE READING AT OWN RISK!
READER DISCRETION IS ADVISED!


Alright, so the fact that we get above 300% CV increases suggests that the actual modifier may be even larger, since lots elements during combat do not contribute to final CV. One that comes to mind is 400%.
As said, this can only be observed in attacks by Germans in Heavy Snow during Winter 41 (show me similar Results in other Weather/Dates if you have any !!!).

The normal maximum should be 100CVx1.25x1.25=156% (I often go with 155% for the sake of ease).

Now as mentioned before, a possible number could be 400%. The question is how these could be achieved.
What stood out to me is that the ERRATA (posted above) uses "/2" and not "x0.5" as modifiers, this is no proove but cought my attention.
As before said the Winter Rules only mention Defender's CV, but I will try to include the numbers/modifier we have to "prove my point" - if I have any, I was called chasing rainbows in the past, so it may just be me having rainbow-fever-dreams <3 .

Variant 1:
Assuming that Winter Battles (Attacks) are using the same twice x1.25 rolls and additionally using the "Winter penalties" in some weird way, we can make the calculation of:
400_1.png
400_1.png (1.78 KiB) Viewed 698 times
The 0.625 are derived by dividing the normal 1.25 modifiers "/2", so 1.25/2=0.625
(I've told you to read at own risk! :lol: ).


Variant 2:
This one is the less brain damaging variant.
This one simply assumes, that the stated "/2" was intended to reduce CV, but instead dividing by 2 or multiplying by 0.5 it divides by 0.5. This one can be interpreted by assuming the passed roll uses "x1.25" and the failed roll uses "/0.5", so the follwoing example would be 2 failed rolls (for all elements - if it works like that).
400_2.png
400_2.png (1.37 KiB) Viewed 698 times
...or there is some completely different shenanigans going on, brain-damaging content ends here. ;)
Alright, that's it.
As said, if anyone has similar attacking results under other circumstances (weather/date) post them here in the Thread and I am proven wrong, which I wouldn't mind. Maybe then my sample size was too small looking at guessed 200+ PvP combat results from T1 till T55. It may also be related to pre battle DISruption, that's also possible, but quick testing gave no obvious results, while Heavy Snow did.

In my case it is the opposite, I love this type of contributions. It is true that it takes me 4 rereadings to fully understand everything :o ... but I think they are very constructive posts. At this point, detecting bugs by unraveling the guts of the game (and showing them to others) is something that I greatly appreciate.

There are multiple recent AARs on Discord showing big CV increases like that for German attacks in first winter heavy snow. It could be something that changed in a recent version since I don't recall hearing much about this issue previously. The other problem is that German SUs in combat don't seem to be affected by blizzard penalties now. I know there were some changes to the blizzard logic recently that were aiming to eliminate penalties for entrained units. So, I wonder if those changes had some unintended consequences for German attacks and/or German SUs in first winter blizzard.

The SU's do take blizzard losses, although at a less rate than normal units per 8.6.1 in rulebook. I can say that is the case in my game coupled with a good rotation you can keep them in very well working order. I do have many stug's in bad condition though :(

In my game I am "NOT" cheesing the system with units on Trains to try and defeat the blizzard effects. My units, and my Panzer Divisions are suffering Blizzard effects BIG time on PZ's. At one point I had only two PZ Divs with workable tanks all the others being damaged by the blizzard. I can tell you that I am "NOT" in contact with the enemy with the majority of my army maintaining 2-4 hexes aways from the Soviets. With this retreat I have been falling back on Stockpiles of supply in depots I have been saving since turn 4+ in key places. I have also turned on replacements all winter and have kept my divisions pretty much full supply and full TOE with supply level 3 during the whole blizzard. Not to mention almost all my units have high AP. Does all this make a difference?

I don't have time to read through this in detail now, but I will say that Gary mentioned to me that he saw some "first winter" modifiers in the code that were kicking into the CV calculations. However, with the quick look he made, he couldn't be sure that some of these routines he saw were still active or not, and I was focused on finding out the normal info, so we didn't try to figure out what first winter mods were active. This is likely another case where Gary made changes to the code/design faster than we could keep up and document. I'll mark this to review your post in the future, but it wouldn't surprise me to find additional leader mods that are not documented, or are incorrectly documented.

If you've got a save we can use to run one of your attacks where it appears that attacking German CV goes up because they are in heavy snow, please attach it. Thanks.

It's an older game Version PBEM PvP (As Dev you do not need the passwords, right?), results are the same as in current games. Doing like 8 Attacks gave 2 of such cases (screens attached).

so if there is some 1st winter effects kicking into bonus CV shouldn't that be to the favor of the soviets not the Germans?

Just saying....seems ridiculous the CV multipliers the Germans are getting in 1st winter when they should be in the hurt locker, not doing multiple strong attacks every turn against the Soviets.

Would be based on leader roles whatever the outcome of this thread is. As such I would argue the point that the Germans have the better leaders and able to make better roles.

There are already enough delimiters in the game for Germany for the 1st winter and additives for the Soviets without adding/subtracting more. The overall questions is, "is there an artifact left over affecting the outcome".

Yup, looks to be the case and substantiates the SU's taking losses per my post :)

As far as I can recall from games in the distant past, Axis were not getting boosted CVs from 1st winter attacks. This looks to be a recent change in the code.
If it was always there then it is a bug that had not been spotted before.
Personally I wouldn't want a player to be taking advantage of it in my games.

Be good to know if this is a bug or SUs in winter(not really being affected) and massive CV bumps are WAD.

I noticed this in my game vs tactical to the SUs sitting in the Army HQs weren't bothered basically at all by the weather. As at first I tried to put the HQs with forts or cities but then noticed they didnt take damage so didnt matter if the HQ was just sitting out in the open.

SU's should probably be affected by the weather even if in HQs if they arent at current....makes that city and fort space even more important to also house the Army Support staff/SUs

Thanks for the saves.

We're pretty sure that, however the system is working, it's been this way since v1.00.07. We found a task that adjusted the display values that we worked on right before release and it came out just after the initial release. After a brief discussion with Gary, his best guess is it's something about how we're displaying CV values on the map that doesn't match up with the pre-combat value and/or the after combat adjustments (some cannot match because they are multi-level die roll dependent in combat, so we have to estimate what the impact might be in the pre-combat/on map values). It's likely WAD, but confusing due to how things work versus how they are displayed. Also, there are some undocumented adjustments going on in the first winter, that are intentional. One is that Axis non-mountain/ski units take a bunch of disruption at the start of the combat if they are in heavy snow (possibly only from Dec-Feb), whether they are the attacker or the defender (I couldn't find it in the manual, but it's always been in the game). There are some leader rolls that come into play in here that I don't think are documented anywhere.

We'll look into it further to make sure it's WAD and try to document what we can.

If Axis support units aren't affected by pre-battle disruption (or if support units penalized by pre-battle disruption can still fight when attacking) then that is an enormous way to blunt any Soviet winter offensive through artillery SUs.

Should be some kind of issue displaying CV in the combat. That unit was displaying in the map, if I remember correctly, 10-12 CV. It was supplyed and higher than 50 CPP so 2 CV seem for me ridiculous.
