Math formulas

Mark, Can you post it?

Okay let me take a stab at converting it into a form that works well on a forum:

Here's the numbers that I've found through testing.

5% percent of range = 100% Penetration
10% percent of range = 100% Penetration
15% percent of range = 100% Penetration
20% percent of range = 100% Penetration
25% percent of range = 82.5% Penetration
30% percent of range = 79.6% Penetration
35% percent of range = 75.8% Penetration
40% percent of range = 72.8% Penetration
45% percent of range = 71.2% Penetration
50% percent of range = 66% Penetration
55% percent of range = 62.8% Penetration
60% percent of range = 60% Penetration
65% percent of range = 55.6% Penetration
70% percent of range = 52.8% Penetration
75% percent of range = 49.8% Penetration
80% percent of range = 46% Penetration
85% percent of range = 42.6% Penetration
90% percent of range = 39.6% Penetration
95% percent of range = 35.4% Penetration
100% percent of range = 33% Penetration

So let us say we want to find the penetration of a weapon with say a 5 AP penetration and a range of 20, at say, 50% of it's range?

Firstly, we take the range (20) and multiply it by 50 to get the weapon's maximum range in meters, which is:

20 x 50 = 1,000 meters

50% of the weapon's maximum range is:

1,000 x 0.5 = 500 meters

Now we can figure out the penetration.

The penetration at 50% of the range is 66%; so

AP Penetration (5) x 0.66 = 3

So at 500 meters, the weapon will have a penetration power of 3.

Please note that this is the *AVERAGE* penetration; you'll find from time to time, your weapon will penetrate a little less or a little more, and a few times will massively overpenetrate or underpenetrate; I *think* the frequency of these occurences and how often they favor over or under penetration is linked to warhead size.

I *think* this is SPCAMO's way of simulating the effects of shell diameter vs armor thickness; the Soviet 122mm gun in WWII was very effective against German Heavy Armor because the shell diameter at 122mm was bigger than the armor thickness that was opposing it.
