Time to replace de Marre's APCR "equation" with something grounded in reality

As we all know from pages of history, Jacob de Marre wrote his infamous APCR equation after a 3-year-long excessive water drinking period CENSORED BECAUSE WT COMMUNITY IS FRAGILE, during which he survived several physical altercations resulting in minor bodily harm CENSORED BECAUSE WT COMMUNITY IS FRAGILE and at least 1 attempt to break a light pole using his famously thick skull.
As expected, the “equation” in its original form looked as below:

APCR = poop.

Jacob’s 7 year old evil cousin Erram Ed Bocaj made it better, but only slightly - because we can’t expect too much from a person who shared at least some of the ancestors with JDM.

Anyway, problem with de Marre’s equation, even with improvements, is that it returns poop for any real life decently performing APCR.
20mm Pzgr 40? Turns into absolute …
20mm DM43? Shatters on 10mm side of ZTS63, takes 100 hits to kill z Shilka, and similar amount of shells to destroy Hellcat.
Why?
Because the “APCR = poop” is the grand mathematical rule behind the formula.
Meanwhile IRL at 1000m DM43 had performance between russian 30mm AP-T and API shells, and that INCLUDES penetration at 60 degrees from vertical.

Now, hear me out - if JDM’s equation basically NEVER returns results even close to realistic, then maybe, just maybe, we should, you know, look for something better instead of basically ruining the entire class of ammunition, including every 20mm armed vehicle that has no access to APDS, but also including poor A10, which also suffers from bad APCR shell, even if that one is arguably “less bad”.

BTW, interesting fact, both Shvak 20mm API and Vya 23mm API were steel-cored APCR. Yet in game they are treated as full caliber AP-I shells. I wonder why… Maybe if APCR wasn’t so bad, nobody would cry if these 2 got fixed, hmmm?

Unfortunately WTs APCR is trailered to work with Soviet APCR, which have very low penetration when only looking at the penetrator size and weight.

Unfortunately Gaijin didnt saw it necessary to have a calculation that also gives western APCR shells realistic performance.

The only time they did something to change this was when 14.5mm API(c) had the same pen as regular API.

Even the post-war Soviet 85mm APCR is hardly an improvement over the, rather underwhelming, WW2 85mm APCR.
Even though the new round should be much more powerful.

But since penetration in WT is basically irrelevant and damage much more important, APCR is hardly useable anyway.

Well, I would love to use something else on Ystervark or R3, but you know, you have a choice between APCR and HE, and HE and APCR, and also lots of APCR and little HE.

Good APCRs are kneecapped by being modelled on russian APCRs in game.

all pen calculators for AP, APCR and APDS lowball figures too.

meanwhile APHE overperforms, thanks gaijin

@Caernarvon02 @KillaKiwi I would be perfectly happy with russian APCR overperforming a bit, if that meant normal APCR would get more reasonable performance.
Right now f.e. Bf 109 G2 edit: of course I’ve meant 110 G2 with its 37mm APCR cannon is the saddest vehicle ever. That thing penetrates nothing and delivers 0 damage.

Also APCR buff would be a good moment to change Shvak and Vya API to rather bad APCR too, lol.

would help move things like the ratel 20 and marder away from ww2 tanks.

Im very much for that

And also that French thing with 2x20mm firing at 100000 ROF with like 1200m/s muzzle velocity.

Didn’t know M302 was Soviet.
Better go tell the American military that their rounds are Soviet.

What are you even talking about?

American 90mm APCR is the best performing in the game, by far.
Like the next best APCR is German… and it’s not even close to M302.

Same high angled pen as M82, and vastly more lower angled pen and flat pen. M302.

It’s still underperforming, and so do 90% of APCR shells.

Just look at M41A1 APCR vs. APDS.

They both use the same tungsten penetrator, yet APDS has 300mm pen while APCR only gets 206 with Gaijins amazing calculator .

I am fairly certain that you mean Bf 110 G-2 not 109 with 3,7 cm.
A 109 with 37 would be awesome tho.

Of course. Weird… Anyway, point still stands.

Bf 109 with 37mm with APHE,. lmao.
But we can’t even have Ta-152C3 with 30mm APHE belt, so there’s that.

id honestly rather all shells over perform then just one for consistency so all shells such as solid shot apcr and APHE of same caliber should do roughly similar damage

without overpressure tanks would change greatly
things such as the jumbo 75 would need to be dropped to brs that the enemys cant pen them it would cause big problems

so my solution would be to double the spall of solid shot by 2.0 multiplier so it equals aphe then give APCR a 1.5 damage multiplier then fix the desparity between APCR rounds as some rounds such as 90MM APCR on the american M36 can go through a panthers front plate which makes no sense since if you try it with other APCRs like the 88MM from a tiger 1 it cant

but to prevent apcr from becoming op the more pen it has less damage multiplier it would receive so if a APCR round does 230mm of pen it receves a lower multiplier than a 190mm pen APCR

This was suggested before and the answer remains the same, it wouldn’t be anywhere near the same performance as APHE because it doesn’t generate spall in a spherical area.
You can kill a tank by shooting its cupola with APHE but doubling or even quadrupling the spalling won’t make this possible for AP

just make the spall spherical problem solved

Now AP and APHE shells perform exactly the same and the distinction doesn’t exist anymore so might as well call both of them “anti tank shells”

At this point we could give all tanks same mobility, armor, reload, etc. with only difference being aesthetical.

the only thing is solid shot has way more pen than there APHE counter parts so it makes up for less damage depending on where you shoot i think they should just make damage more consistent
