Step 1 A.V. column holds a prose AV-adjustment note rather than a single value; the adjusted acid value 32.66 is extracted with the full cell kept verbatim (polysemous A.V., medium confidence). Step 3 procedure is a single feed step ('Feed 25 min @52-55 deg C'); the Time (h) cell for Step 3 was blank in the CSV and the 55-58 value sits in the Temp column, so only one procedure event is emitted and the step time is low confidence. The two trailing 'Iodine value' rows (57.2/3 and 25.7/6) are stray extras outside the fixed columns, preserved as payload.results measurements (never dropped). The 25.7 stray matches the IV-25.7 already reported in Step 2. The 'Feed' entry in the Step 2 A.V. column is read as a process note (this step receives a feed), not a measurement."
