Certain
The spec and the drawings agree, and the count is clean. Certain lines stay out of the review queue. You can still open one to see its source.
Maybe
Takeoff Tool has an answer but wants it confirmed. The line opens with the guess next to the spec text or the sheet it came from. Maybe lines are the review queue.
Not sure
It will not stand behind a number. The line says what it measured and what is missing. It parks the line and does not invent a quantity.
Why three grades and not a score
A percentage hides the lines that matter. Three grades tell you where to spend your time: skip the certain lines, walk the maybes, and get an answer for the not-sure lines before you price.
