recoil pattern · 30-round burst≈ 6.5s

Heuristic from v-recoil 37 / h-recoil 42. Bottom = first shot, top = 30th. Tighter cluster ≈ easier mag dump; wide spread ≈ tap-fire territory.

Approximate falloff: flat to 12m → linear decay 1.0–1.5× eff range → ~42% damage floor beyond. Heuristic only; real per-pellet pen and armor curves come from /penetration.
