The method
We start from the question a reader is trying to answer and the specific pages likely to answer it. Each page is read in full, and the line that holds the figure is stored as written, with its address and read date.
Every candidate sentence is accepted or rejected by a reviewer, who writes down why. Each source then counts once in the median and range, or once for each breakdown it prices. Pages that state nothing are listed as silent, not estimated, and each dataset is read again on schedule so changes show up.
