How it works
Sell-through = items sold during the period ÷ items listed during that period. Velocity divides sales by the period length; clear-time estimate uses current active stock at that same pace.
Example: 8 sold from 20 listed over 30 days is a 40% sell-through rate and about 1.9 sales per week.
