The method
The work starts with a question and the URLs of the pages that should answer it. We read each one and record the figure exactly as the page puts it, with the link and the date of the read.
A person reviews each sentence before it counts and records the reason when one is turned away. The summary figures use one number per source, and one per breakdown where a source prices several. A source with no figure stays blank, and repeat reads show how the numbers change over time.
