Correlation between Bullet Damage, Health, and Penetration

Bullet Damage, Bullet Health, and Bullet Penetration have a very close correlation with determining total bullet damage. This page will hopefully explain the intricacies of the stats and help players to make better decisions on their builds.

Definitions
Bullet Damage (D) - Determines how much damage a bullet causes upon impact.

Bullet Health (H) - Determines the health of the bullet.

Bullet Penetration (P) - Determines how much penetration the bullets have.

Damage Per Second (DPS)- The combination of all the stats.

Let Total Bullet Damage be defined as follows. D * H * P = DPS

Mechanics
Damage is the raw stat value. For example, if a bullet has a damage value of 3, it will deal 3 damage per health.

Health is the raw health value. The more health, the more damage overall. For example, if we use the above bullet but give it 5 health, it will still deal 3 damage per health but will now deal 15 damage overall.

Penetration is a damage modifier that determines how likely the bullet is going to travel through the entity. The higher the penetration, the more likely it is to travel though. The lower the penetration, the more likely it is to just bounce off. Diep.io entities have very low penetration in comparison to most Woomy-Arras.io entities. It is currently unknown what the actual base modifier is for Penetration. While it is not as easy to factor Penetration into the actual DPS formula as it is for Damage and Health, it is generally accepted that a higher Penetration will deal more damage, as it is less likely for the projectile dealing said damage to be bounced away from the target.
