7 · SANITY CHECKSa fail sends you back to box 6 → Step 7
CheckShould be YoursPass?Failure means
Drying share43–51 %— high = late yellow · low = rushed
Maillard share33–39 %— low = too little browning
Development ratio12–20 %— under 12 % = under-developed
Development ceiling< 4:30— over 4:30 mutes any roast
