What to look for in media scans?

Hi, I’m kinda new here, and have become quite interested in the various topics.

There are alot of posts with graphs of scanned media.

Can someone please explain how to “evaluate” those posted scans?
what are we looking for?
PI Errors, PI Failures, Jitter, C1, C2. PO Failures?

What specific values would warrant a CD to be tagged as bad?

And if the answer to this question is somewhere in the forum,
can someone direct me to it please?

much thanks
