Where the numbers come from
The odds are from Perfect World's published table. Each grade is five times as likely as the one above it, and a knife or pair of gloves is 2 for every 5 Coverts. The knife trade-up is in Valve's October 22, 2025 patch notes.
Prices are the lowest current listing on the Steam Community Market. Case prices are read every night, skin, knife and glove prices once a week, and the price history is Steam's own daily median. What is in each case comes from the game's item files.
Valve does not publish wear odds, so the value of a drop uses the float model players have measured, scaled to each skin's float range. Pattern and float premiums, like a Case Hardened Blue Gem, are left out. They can be worth far more than the average.
