Assumptions
  • Open cost = case price + key price.
  • Skins within a tier are equally likely; StatTrak is an independent 10% roll.
  • P(wear) = share of the skin's float range inside each wear band.
  • Unpriced outcomes (9%) are excluded from the EV.
  • Values are Steam Community Market snapshot prices, not net of market fees.
