Rarity odds
Expected value
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 (4%) are excluded from the EV.
- Values are Steam Community Market snapshot prices, not net of market fees.

The Spectrum 2 Case was released on 2017-09-06. One opening costs $22.43 ($4.24 for the case plus $18.19 for the key), which ranks 22 of 42 cases from cheapest to most expensive. Its modeled expected return is $3.40 per opening, a modeled ROI of 15.1% (38 of 42 by ROI). That is an average over many openings, not a prediction for any single one.
