WIth the recent Q&A we got some more info on the dmg and penetration RNG distribution.

So I did some calculations with the info we have from WG:

-normal distribution

-67% to be between -10% and 10%

With that I got this distribution:

The x axis is the percentage deviation from the avg roll.

With that we can calculate the chance of every roll accuring.

Or if you want to aapt if for 1 particular tank:

with sigma= 10,515% of avg dmg

m=avg roll of tank

A=1.017736918

A couple of facts about it:

-37% of shots are between -5% and 5%

-67% of shots are between -10% and 10%

-86% of shots are between -15 and 15%

-96% of shots are between -20% and 20%.

Then the accuracy, with this information:

http://ftr.wot-news....ange-explained/

I was able to calculate that pre 9.6 accuracy was a normal distribution with sigma= 0.5225. But in 9.6 they changed it to a customized distribtion that looks like this:

-28% of shots fall into the inner 20% radius of the circle.

-51% of shots fall into the inner 35% radius of the circle.

-70% of shots fall into the inner 50% radius of the circle.

-87% of shots fall into the inner 70% radius of the circle.

-97% of shots fall into the inner 90% radius of the circle.
