Here's why: the basic dispersion of the Strv S1's gun is 40 cm per 100 meters which means for 300 meters shot the shell will land in 1.2 meters from the desired point in any direction.

Brothers in arms adds 5% improvement (0.02), **No it is not that simple. BIA adds 5% to the training level of the crew man in his major qualification. Thus it makes the gunner 5% more effective. He will therefore Aim a little faster, he will be a little more accurate, and if a tank has a turret the turret will turn slightly quicker.**

ventilation adds 5% (0.02). **No it is not that simple. Vents also adds to the crew skill in the way that BIA does.**

That's 10% of the base dispersion. 10% of 0.4 is 0.04. **This is therefore straight up wrong the two 5%'s do not get added to base dispersion in a calculation in the way that you have done it.**

Therefore the dispersion should become 0.36.** No that figure is wrong.**

If you add a directive (ventilation for 2.5%) that's 0.01, so it should become 0.35. **No that is a misunderstanding of how directives work and your figure is wrong.**

Food gives 10% improvement from the base dispersion which means 0.04. 0.35 minus 0.04 makes 0.31 dispersion. **No that is not how food works and again your figure is wrong.**

Instead, with BIA and ventilation the dispersion drops down to 0.38, adding the 2.5% ventilation drops it down to 0.37 and with food it becomes 0.36.** No it does not your figure is wrong.**

**To see your errors read the wiki as a starting point. Here = **http://wiki.wargamin...t/en/Crew#Perks

And these things don't work properly on camouflage either. **Thats because you have failed to work out how camo works, possibly because you have failed to read the wiki.**

**Try reading **http://wiki.wargamin...ics#Visibility **before making even more errors and spreading even more false information.**

**The basic camo equation is = ****camoFactor** = **baseCamo** * (0.00375 * **camoSkill** + 0.5) * **camoAtShot** + **camoPattern** + **camoNet** + **environmentCamo**

The basic camo is 24.05%.

Camo net adds 15%, crew skill adds 19.35%, ventilation - 5%, BIA - 5%, additional ventilation - 2.5%, food - 10%. **Wrong equation!**

Sum these numbers - they make 80.9. **Wrong!**

Which means that if you knew math, the camouflage of the Strv S1 should be 80.9% when stationary (in siege mode)!!! **Wrong**

Instead, with BIA and ventilation, the 2.5% ventilation, camo net and food the camo factor is only 66%. **Because you used the wrong figures**

**Let's look at an example to see how it all comes together;**

Say our spotting target has a baseCamo coefficient of 25% or 0.25 while standing still and 15% or 0.15 while moving the hull. The camoAtShot factor is 25% or 0.25 as well. The entire crew of 5 has 100% Camouflage skill level and the Commander has 100% primary skill level. Improved Ventilation equipment is installed. Our tank is sitting completely inside of a dense bush and has not been moving for more than 3 seconds.

The effective camouflage skill is:

- (100 + 5 + (100 + 5 + (100 + 5) * 0.1) * 4) / 5 = 113.4

Should this calculation be confusing to you, remember that you need to factor in both the bonus from Improved Ventilation equipment as well as the Commander bonus. It would, however, be understandable if the calculation above still seems confusing, because there's no way to tell what those figures relate to unless you spend some minutes figuring out the equation. To make things easier for you, here's the above numbers explained:

- (CommanderSkill + VentBonus + (CrewSkill + VentBonus + (CommanderSkill + VentBonus) * 0.1) * NumberOfNonCommanderCrewMembers)) / TotalNumberOfCrewMembersIncludingCommander = X

Now we can calculate the camouflage factor using the value for the effective camouflage factor:

- 0.25 * (0.00375 * 113.4 + 0.5) + 0.64 = 0.8713125 (87.13%)

As soon as our tank starts moving out of the bush, the camouflage factor is as follows:

- 0.15 * (0.00375 * 113.4 + 0.5) = 0.1387875 (13.88%)

The only thing you've done right about this tank is the view range, altough the actual view range ever since game version 1.0.0 is more like 5 meters **No proof given, wild allegation**

P.S. If I check my other tanks, I'm quite sure I'll find the same discrepancies with them too. **If you do the maths correctly there will be no discrepancies. If you do made up maths like yours without reading the wiki first and doing the equations wrong then you will find that your fake figures are different from the games calculations.**
