At every skill point we pick the recipe with the lowest expected cost per skill-up: reagents at today's lowest (or the vendor) minus what the result fetches from a vendor (the safe minimum; the auction house is added for the few the market takes in about two days), divided by the classic skill-up chance (orange always, then falling to zero at grey). Crafts are expected counts, so luck can move them a little. Trainer recipes count as learnable 15 points before they turn yellow (their exact level isn't in the game data). Patterns that bind on pickup are left out; tradeable patterns that aren't listed right now are flagged. Trainer fees and the rank-ups (75, 150, 225) aren't included. Buying hundreds of a reagent will cost more than its lowest price.
