Profit per craft after the 15% AH cut, with reagents at today's lowest (or the vendor). Products are priced at today's lowest, never above their usual price. Potential = profit per item × items sold per day: what the whole market moves, not what you alone will sell. Trainer recipes count as learnable up to 15 points before they turn yellow (their exact learn level isn't in the game data).
