Steps 1 and 2 each have one condition row per material row; rows read positionally as sequential ramp stages (Step 1: 45-50/0.5 h then 70-75/4.5 h N2; Step 2: 77-81/2 h then 78-82/6 h N2) - the table does not state whether the second material is staged or present from the start, so no staged-addition claim is made. Step 3 merges both Step-1 and Step-2 products (Steps 1 and 2 presumably parallel); the '(85)' and '(15)' qualifiers in the Step 3 material names were recorded as rm_pct with qty 106.25 g and 18.75 g verbatim. Step 1 A.V. cell is the bare '46.34' in the A.V. results column; emitted as A.V. medium confidence. A small 'Iodine value / Time' table sits in the Step 1 Other / Step 2 Name columns (IV 62.2 at Time 2; IV 46.5 at Time 4; IV 35.6 at Time 5); recorded as three 'iodine value' measurements on Step 1, medium confidence. Step 2 A.V. cell is prose 'AV-0.3/ Amine 260/IV-34.5' - split into acid value 0.3, amine value 260, iodine value 34.5 per the polysemous-A.V. rule. The Step 3 final-product property set 'AV-37.97/ Amine-27.8/HV-83/IV-5.' physically sits in the Remarks column rather than a Step-3 results column (no such column exists in this sheet); emitted as Step 3 results with low confidence to flag the placement, not dropped per the stray-extras rule. Remarks pigment assessment (row 108) recorded as observations. Step 2 name cell ' Epomine SP- 018' has a leading space in the source."
