So here's something I've been developing over a week or two so that my future science fiction story has somewhat realistic vehicles that when you do the numbers on them; they come out as being 90 percent "About right", rather than me just pulling numbers out of my ***.
And as I developed it more, and added more detail after buying a Jane's Armor and Artillery Upgrades 95-96 book, I thought: "Why not call it TankSharp?", and further thought "I wonder how far we can go with it?"
So here's the link:

I know that there are probably some limitations in it; most notably:
• Does not allow for Side or Rear Hull Sloping. (see last number)
• Does not allow Curved Armor (such as Cast RHA Gun Mantlets).
• There is "missing" armor on the turret whose weight is not accounted for if you slope all four sides; because I did not have the knowledge or skill to figure out the calculations required to do that (I only passed basic High School Algebra a looong time ago). I decided to allow complete sloping of all four sides on the turret, since the area that goes "missing" is very little compared to what would go "missing" with it applied to the hull.
Basically, Take a look and see how it works; and please be kind to me this is my first attempt

In SPCAMO game terms, the BMP-1 of the datasheet has a rating of:
Hull (front Sides, rear)
4/2/2
Turret (front Sides, rear)
3/2/2
On a combat weight of 13.81 tons.
However, if we add 12.7mm (1/2" of SHS) applique armor, with it's 1.23 efficiency rating against KE attacks to the front and sides for a total of 1.58 metric tons additional weight; that rating goes up to:
Hull (front Sides, rear)
10/4/2
Turret (front Sides, rear)
5/4/2
However, SHS is not cheap, it's something like twice the cost of conventional RHA, and can only be rolled in relatively thin layers.
