A structured worksheet that computes first crack, development, and drop from your bean — then keeps the plan next to what actually happened.
Every field ties back to the same time-ledger math professional roasters already use on paper — now it computes itself.
Anchor first crack by cultivar, then let refinements, bean condition, and batch size sum into a plan you can defend.
Drying, Maillard, and development ratios validated against known bands before you roast.
Log milestones at the machine, attach an Artisan .alog reference curve, and see plan against reality.
Cultivar, process, bean condition — the worksheet pulls in the right reference numbers automatically.
Watch first crack, development, and drop compute live, with every ratio checked against known-good bands.
Log milestones as you go, then compare against an Artisan reference curve after the roast.
