Create HELP topic containing explanation of error messages in Secure Ripping Log.txt

[geogherkins]

I am trying to get a secure rip from a damaged disc and need to interpret the contents of the Secure Ripping Log.txt but I am not finding any reference documentation for the error messages. Please create documentation.

For example!

AccurateRip: Inaccurate (confidence aaa)
AccurateRip: Accurate (confidence bbb)
[DiscID: ccc-dddddddd-eeeeeeee-fff]
CRC32: nnnnnnnn AccurateRip CRC: nnnnnnnn (CRCv2)
Frame LBA matched xx / yy (c2 dropped zz) [c2 best match]

What do all of these values mean?
