2 · BLENDskip if single-origin → Step 2

2.1This lot is: single-origin — skip this box blend or community lot

2.2Component	Group	Process	Share %	FC anchor

2.3Method: dominant (≥60%) weighted average split-roast, blend after

2.4Resulting FC anchor → ledger line 1 |2.5Resulting processing modifier → ledger line 8

6 · TIME LEDGERmethod & why → Step 6

1	Cultivar/blend anchor from 1.4, or 2.4 if blend	—
2	± Refinement — from 1.6 0 first cook, else Step 12	—
3	± Bean condition — from 5.6	—
4	± Batch size vs. Step 9 reference weights 225 g ≈ 1:30–2:00 later than 200 g
A	FIRST CRACK	—
	B · YELLOW / MAILLARD — informational only. NOT summed into C.
5	YELLOW = A × 0.56	—
6	MAILLARD = A − line 5	—
	C · DEVELOPMENT — sum ONLY rows 7 + 8 + 9
7	Development base — from 4.3	—
8	± Processing modifier — from 3.2, or 2.5 if blend	—
9	± Cultivar dev modifier — from 1.7	—
C	DEVELOPMENT = 7 + 8 + 9 only	—
D	DROP (end of roast) = A + C	—

7 · SANITY CHECKSa fail sends you back to box 6 → Step 7

Check	Should be	Yours	Failure means
Drying share	43–51 %	—	high = late yellow · low = rushed
Maillard share	33–39 %	—	low = too little browning
Development ratio	12–20 %	—	under 12 % = under-developed
Development ceiling	< 4:30	—	over 4:30 mutes any roast
