Values marked our reading are our classification of what the source says — the source does not print them in those words. The quote below is the evidence for each one; judge it yourself.

What the source says

Accuracy class

The source prints this value inside the passage below but does not name it there. The passage shows where it appears; what ties it to this record is the position on the page, not anything the passage says.
