(Updated)

This first image is a bubble chart showing all guns listed on tanks.gg that have non-premium AP, APCR, or HEAT rounds, excluding the "Nameless" tank. The area of each bubble represents the number of guns of identical caliber and damage.

The curved line represents the function D=K((R^3)+(R^2)+R) where "D" is average damage upon penetration, "K" is 20 hitpoints of damage, and "R" is the shell radius (NOT diameter) in inches.

Side note: I had to download Microsoft Office, as Excel Online does not have bubble charts. I had to create the line out of 2000 small bubbles, since bubble charts are not an option when making a custom combination chart. My computer almost crashed when first plotting this chart.

The second chart (below)(which I published calling it "mostly useless", which it is) shows outliers when comparing the damage of standard AP/APCR/HEAT shells to their caliber.

The x-axis measures cross sectional area in square inches ((((mm/diameter)*(1"/25.4mm)*(1diameter/2radii))^2)*pi).

The y-axis measures average damage upon penetration, in hitpoints.

The curve is the same as in the last chart, but scaled to fit the new x-axis, which is by area instead of diameter.

In regards to the second chart (which was actually the one I made first):

I tried to include all outliers and be unbiased. I compared caliber to damage for all guns in the game without recording the tank name, using an excel spreadsheet. The requirements for being included are **<75%** curve height or **>140%** curve height. I included the **PTA & Leopard**, as they came close at **138%** curve height, and all other 91mm+ guns are <130% curve height. NOTE: This **does NOT apply to the "Comparison" or "Reference" **guns. Note: I did not check guns that do not have any non-premium AP, APCR, or HEAT rounds. This means that the 152mm T49, with standard HEAT was checked. Meanwhile the 105mm M4A1, with only premium HEAT, was not checked. In the M4A1's case, the Pz. IV H has the same damage and has AP rounds which were checked, so it obviously wouldn't have made the chart anyways.

**Exclusions**:

"Nameless", the tank is on tanks.gg but not available in the game.

40mm guns with 55 damage (7TP & Matilda), since Cruiser IV & Covenanter have the same caliber and more damage (60).

45mm guns with 70 damage (T-50 & stock MT-25), since 10TP & 14TP are nearly identical in caliber (47mm) and have more damage (75).

Thinking about it now, I probably should've excluded the Ke-Ni and Chi-Ha
