Box Cooldown — Boxes have an internal cooldown (exact duration TBD). Farming too fast may yield fewer than shown. Currently calculated without CD cap.
Box EV — Expected Value = Σ(drop_rate × market_price). Prices fetched from Steam Community Market.
Normal vs Boss Box — Normal boxes drop per wave, Boss boxes only on boss waves. Boss boxes are rarer but higher quality.
Market $/hr — Theoretical income = (NormalEV × normal/hr) + (BossEV × boss/hr). Only Legendary+ is tradeable.
EXP Penalty — Over-leveling a stage drastically reduces EXP gain. Red = severe penalty.
Calibration — DPS model: clear_time = HP/DPS + waves × wave_time. More points = better accuracy.
