I'm sorry if this was explained somewhere, but I was unable to find the answer when searching this forum:
Why the value of APEffective[0] value in squads.csv file is almost always set to a value much lower than 100? My understanding is that the distance of 1 tile in game corresponds to a really close range IRL terms, about 100m, and there should not be this much penetration loss for tank/anti-tank guns, at least not even close to ~20% drop from the nominal value.
Why not just lower the nominal value by the same amount if the numbers in APAttack[0..1] column are never used directly? Or do they? If any devs are still reading these forums, pls help me make sense of this.
