Paired on the measurement’s name only, which cannot know that three span lengths sum to the deck length. Step 3 works these out properly for every item it matches — reading every crop behind the item, deriving what the drawings imply and showing its arithmetic. This item has not had that pass yet; the button runs it for this one.

  "description": "This crop contains a repeating series of eight railroad cross sections at 50-foot station intervals from 302+00 to 305+50, each showing the existing railroad right-of-way limits, centerlines of the existing track, future track, and access road, with corresponding elevations at the top of rail/track and along the access road grade. The sections illustrate the existing ground profile (dashed line with a dip for the access road) relative to a common elevation grid (150–170) and depict the relative positions and elevations of the existing and future track alignments alongside the access roadway. This sheet is titled 'RAILROAD CROSS SECTIONS' and documents survey/design elevations for grading and track alignment along this corridor."
