Definition

The Ballistic Score is a synthetic stat in DayZ that measures the shooting efficiency of a projectile. It focuses on muzzle velocity, durability, and supersonic quietness. Additional ballistic properties such as rate of fire (RPM), penetration power, and damage retention are displayed separately but not included in the final score. The score is normalized on a 1–100 scale, where higher is better.

Formula

Speed Score (muzzle velocity):

\(SpeedScore = \min\!\Big(\frac{ProjectileSpeed}{1000},\ 1\Big) \times 100\)

Higher projectile speed means flatter trajectory and better hit probability.

Durability (Shots to Ruin):

\(ShotsToRuinScore = \min\!\Big(\frac{ShotsToRuin}{900},\ 1\Big) \times 100\)

Represents how many rounds a weapon can fire before breaking.

Supersonic Quietness:

\(SupersonicQuietness = \min\!\Big(\frac{CrackQuietness}{900},\ 1\Big) \times 100\)

Measures how quiet the bullet’s supersonic crack is (lower crack = higher score).

Final Ballistic Score:

\(BallisticScore = \frac{SpeedScore + ShotsToRuinScore + SupersonicQuietness}{3}\)

This averages speed, durability, and stealth (supersonic quietness) into a single efficiency score.

Where

  • \(ProjectileSpeed\) = muzzle velocity (m/s)
  • \(ShotsToRuin\) = number of shots before the weapon is ruined
  • \(CrackQuietness\) = loudness of the bullet’s supersonic crack

Explanation

The Ballistic Score summarizes how effective a weapon is in sustained combat situations. It balances projectile speed, durability, and stealth (supersonic quietness). Other values like rate of fire, penetration, and damage retention are displayed as reference but excluded from the main score.

Example

If a weapon has ProjectileSpeed = 800, ShotsToRuin = 600, and CrackQuietness = 450:

  • \(SpeedScore = \min(\tfrac{800}{1000},1) \times 100 = 80\)
  • \(ShotsToRuinScore = \min(\tfrac{600}{900},1) \times 100 \approx 66\)
  • \(SupersonicQuietness = \min(\tfrac{450}{900},1) \times 100 = 50\)

Final Ballistic Score = \(\frac{80 + 66 + 50}{3} \approx 65.3\)
