I think the last time that happened was  the German Camo values during open beta, wasn't it?Someone datamined the Camo values, and proved that German ones were bugged. The values got a fix, but the user still got a ban. Of course that was all before my time.


They posted the whole contents of the xml files, there was a lot more than Camo values in there but much of it got overlooked because people were only interested in the camo values which only confirmed what we already knew.

How the penalty is calculated into the formula? :amazed:

Exsample: SU-18

Gun:

Aim time: 4.5s

Shot dispersion factor
- turret rotation: 0.24
- after shot: 4
- while gun damaged: 2


Suspension:

Shot dispersion factor
- movement: 0.24
- rotation: 0.24


Thanks for explaining  :smile:

I only know for sure how to calculate with the dispersion factor "after shot". Because I haven't tested the effects of movement and rotation. But to sum up the previous posts, the formula for calculating the true aim time after a shot is:
t = AT * ln(fDS) * 0.875 / (0.00375*GTL + 0.5)
Where AT is the listed aim time stat, and fDS is the factor "dispersion after shot". ln is the natural logaritm function. GTL is the basic training level for the gunner in %. If you use vents or have the brothers in arms perk, you must add 5 to GTL for each of them. Also on tanks with both a commander and a gunner in the crew, the gunner receive an additional bonus of 10% of the commanders training level.
Now, although I haven't tested it, my guess is that dispersion after rotation is simply the dispersion factor multiplied with the speed value. So for dispersion after rotation for the SU-18 you get 0.24 * 22 (degrees/s) = 5.28
The theoretical aimtimes for an SU-18 with a 100% crew and vents installed would then be:
After shot:
t = 4.5 s * ln(4.0) * 0.875 / (0.00375*105 + 0.5) = 6.1 s
After rotation:
t = 4.5 s * ln(0.24 * 22) * 0.875 / (0.00375*105 + 0.5) = 7.3 s
For a 75% crew and no vents, the aimtimes would be:
After shot:
t = 4.5 s * ln(4.0) * 0.875 / (0.00375*75 + 0.5) = 7.0 s
After rotation:
t = 4.5 s * ln(0.24 * 22) * 0.875 / (0.00375*75 + 0.5) = 8.4 s

But true.

Publishing data obtained by reverse engineering the game files will get you a ban as it is a breach of the Eula/ToS.
You should remember what that case was :)

Yep, moving t-54 had better camo value than stationary been panther II.

Absolutely ridiculous.

Wargaming will do everything in their might to stop leaks from happening that show they manipulate the game.

It also happened when someone during beta published camo modifiers for each tank, he got banned as well and all he did was show that WG favours certain tanks over others.
