TTK simulator

Pick a gun, ammo, target armor + helmet class, and an engagement range. The simulator returns shots-to-kill and time-to-kill for every body part, plus the pen probability behind the math. Built on the same penetration ladder as /penetration.

HP pools — head 35, thorax 85, stomach 70, arms 60, legs 65 (ABI conventions, not literal Tarkov values)
Effective damage = pPen × dmg + (1 − pPen) × dmg × bluntMult; blunt mult depends on plate material
Range buckets attenuate both base damage and pen probability — see /penetration for the full ladder
TTK seconds = (shots − 1) ÷ (RPM ÷ 60). First round at t=0, then n−1 more spaced 1/RPS apart.
Body part rows assume every shot lands on that part. Real raids mix it up — use thorax as the headline number.
