Understanding Winter Offensive Case EV
The expected value of the Winter Offensive Case depends on the current market prices of all skins it contains, weighted by their drop probabilities. Since approximately 80% of drops are Mil-Spec items worth very little, the EV is heavily influenced by the value of the rarer items — particularly the covert and knife/gloves tier.
When calculating EV, remember that the total cost per opening includes both the case price and the key price ($2.49). Even if a case sells for $0.03 on the Steam Market, the total opening cost is still $2.52, making the effective EV calculation require a relatively high average return to break even.
