Main page

Since this awesome thread at the german forum started by Razor666_cgn was a huge success and it was requested to be translated, I did my best:

First the original posting (Behold, it is in german language)
German Version

Now we start with the data on the game. Enjoy.

Guns
Data on the guns: http://wot.ds-graphixx.de/

Bounces

The projectiles and the angles of impact are idealised, to make calculations less complex. Every angle of impact higher than 70 degrees counts as ricochet!
With one exception: If the armor is three times thinner than the caliber of the projectile and the angle is higher than 8 degrees, the shot will penetrate. All shells have a richochet value and an idealisation value. These are 70 and 8 degrees for the most part of the shells. Note: It seems obvious that the explanation from the english forum is out-of-date.

Explanation:
Green:Hit
Red:Bounce
Numbers:Degrees

Equipment
Removed Speed Governor: Increases the power of the engine by 10% and damages the engine with 1 HP/sec.

Optics: Get active after 3 seconds of being stationary.

Camouflage Net: Get active after 3 seconds of being stationary and increases the camo value to 1,99.(I have to test, how this is actually working.) The 25% stated ingame would be 1,25 here. Like this it would be +99% to camo.

Vertical Stabilizer: The spreading while driving is decreased by a multiplier of 0,8. (Example T-44: 0,24x0,8 = 0,19)

Calculating the hits
The 3D model of the hitboxes, posted at the forum, leads to the assumption that WoT uses a quite plain system of calculating the hits. Fuel tanks, ammo rack, gear box, transmission, turret ring, gun mantlet, tracks an obviously the crew. Here are the explanations for the most common strange damages.

Frontal hit, engine down, engine located in the back of the tank -> Engine was not hit, but gear box or transmission were.
Hit once, three modules down -> The shot went straight through the tank/turret.

Every module in WoT has a set amount of hit points(HP). Those are repaired by the crew, but not up to 100%. The ammo rack of a Panzer III for example, has 100HP and will be repaired up to 75HP The crew has a HP rate how fast the module will be repaired. On the Panzer III this is 5HP/sec for the ammo rack. Unfortunatly burns the ammo rack on a Panzer III with 9,5HP/sec, so the tank is toast without a fire-extinguisher
By the way, most of the tracks have a armor value of 15-20, no suprise they break, if you hit them.

So, what happens in case of a hit? First it will be calculated if the hit deals damage. In case of an exterior module is hit (tracks/gun), it is possible that the module absorbs the damage and the tank gets no damage (no HP decrease). If the projectile penetrates the armor, it takes a straight line through the tank and damages every single module/crewmember in its path. In our example with the Panzer III, a projectile hits the ammo rack and still has the energy to get over the 100HP in one hit the tank is instant blown to pieces. Another example, if you hit the rear hatch of a KV with a 10,5cm gun it will be a one-shot as well.

The chances for the loss of a module:

Engine: 45%
Ammo rack: 27%
Fuel tank: 45%
Optics: 45%
Radio: 45%
Gun: 33%
Turret ring: 45%
Crew: 33%

Camouflage Ability
Many people assumed wrong that you are invisible in or behind a bush. Thats not the absolute truth. The tank has to be fully covered and cease moving his hull. Turning yes, back and forth no. Also the ability is linked to the size of the tank. A Jagdtiger has almost no camouflage ability. Here is some data on the camouflage ability of the tanks.

At this point a big thanks to Ijisthee for the diagrams!

The credit coefficients:

The average tank as an average coefficient of 0,65 - 0,71. Except the premium tanks, which have 1,10-1,3. In my opinion the value shows how much credits you get for a kill. The value of the enemy tank x credit coefficient.
American mediums have 0,90 as equalisation for poor armament. This is a assumption!

The ratio of how fast tanks are burning

Name: Burning ratio in HP/second / chance of extinguishing the fire

Ferdinand: 60 / 0,20
JgPanther: 43 / 0,18
JgTiger: 80 / 0,20
Panther II: 90 / 0,20
Tiger: 72,5 / 0,20
Tiger II: 80 / 0,20
Panzer IV: 23 / 0,20
VK4502: 97 / 0,20

IS: 61,5 / 0,20
IS-3: 70 / 0,20
ISU-152: 50,5 / 0,20
IS-7: 110 / 0,20
SU-100: 30 / 0,20
T-44: 65 / 0,20

T-29: 62,5 / 0,20
T-30: 112,5 / 0,20
T-32: 77,5 / 0,20

The ratios are between 10 and 120 HP and 20% to be set on fire. Higher tier equals higher burning ratio.
Except TDs which have lesser ratios due the lesser HP.

The coefficient for the repair:

Name: / Coefficient

Ferdinand: 8
Tiger: 5,95
Tiger II: 7,92
PzIII: 4,3
JgTiger: 8,4
JgPanther: 7,32
Panther: 8,75
Panther II: 10,00

IS: 5,95
IS-3: 7,07
IS-4: 9,18
IS-7: 10,96
T34: 5,34
T54: 8,65 (bad thing, the PantherII seems to be much more expensive)

M4 Sherman: 5,34
Pershing: 10,80
T30: 10,96
T32: 7,92
T29: 5,17
M6: 5,16

Sweet! Thanks for the translation.

Thanks for translating it *scraps his own draft version*

Good job.  

those values could be changed duo to update, couldn't it?

Yes, they do. We try to keep our diagrams up to date. We hope you excuse some delay after new patch

Thankyou for the translation. It was a nice post..

are those numbers datamined? or field tested?
why the top tier german mediums/heavy/TDs/SPGs have a drastic drop in camo rating when the soviet/US don;t ?

Wow, very nice.
One question: I though that camo net comes in play after 6 seconds staying still not three. Which is correct?

EULA-violating material may claim it to be latter, so that's what I would probably trust. Personally I have before assumed that the time was 5 seconds

Great thread,

Now I understand why I'm not driving Panther 2 any more.

1. expensive to reload 105mm gun
2. expensive to repair
3. easily get damaged and burned
4. cammo does not work

so I would like to know what is the purpose of top German medium tank ? Why are Russian tank so OP-ed ?
I will rather stop playing this game than giving up on German armor. It seems to me that I won't continue to play it once it gets released if balance remains like this.

many thanks
M.

This is very interesting. Can somebody explain why top tier German heavy tanks have such bad cam ratio? Look at the Tiger 2 - it's even below the value of KV!!!
Unbelievable...

Why is the IS so stealthy anyway?

Well, the camos of the top german TDs are scewed, just as the ones from german heavies. So this means the ones meant to snipe cant do their job properly, for another extra reason.

It would appear the Hetzer is the ultimate stealth tank.

45% when moving
60% when still
75% when under a camo net

It then gets screwed over by its viewrange of 300m which means all the camo can do for it is keep it hidden until someone is close enough to see... which generally means they can see you too now.


Interesting that the su-85 and su-100 also have 60% and 75% when still and netted but only 20% when moving. Must be the stealth tech in the slopes on the Hetzer that make the difference.

Thank you very much for translation! It's hard to find all this data in one place

Malinovka(aka Campingkova): 1000x1000m

In russian more correctly would be Campingovka
Btw, nice thread. I got one point from it - DO NOT TRY TO HIDE KV/KV-3

Great post. Thanks for the translation

Awesome thread thank you

The top three German TD's must have incorrect camo stats because look at the top three Russian TD's it's not like they are 4 times smaller than German TD's and therefore easier to hide is it?

It's because invisibility factor for Jagdtiger is very low in comparison to for example Object 704
