Interpreting certain AR results Options

[Dario]

Hello there.

There are certain AccurateRip results that have been puzzling me lately:

What would "No match but offset" suggest here? I've read that it's used as some kind of a "pressing-detector", but couldn't understand much (sorry). The second log comes from a rather rare record that I no longer own (and wasn't in AR's database at the time it was ripped), so I'd really like to resolve this. Note that there are no audible glitches whatsoever, and as far as memory serves me, the CD was not scratched or anything.

Thank you for your assistance.
