Can someone point me to a guide to help interpret Accuraterip results in conjunction with EAC results? I see a ton of postings with case-specific questions, but I haven't come across something that gives generalized help for most common situations. It seems to me that this is an important oversight from the multitude of EAC user guides I've reviewed.

Examples of some things that I'm unclear about are:

distinguishing ripping errors from different pressings
handling low confidence values for popular albums
disagreement between EAC and AR
the meaning of confidence for inaccurate rips? Is that the number of people who haved successfully ripped to the CRC returned by AR?

If this guide doesn't exist, could someone with some experience whip one up for posterity on this board? Alternatively, I'd be happy to compile the results of various responses if it proves to be of value to anyone.

Any light people could shed on this subject would be very much appreciated.

Generally speaking, this is the way I translate what I read:

>=1 confidence that it is accurate
Song is accurate provided at least one of the confidences was not a previous submission by me (eliminates even the most remote possibility that I have a consistent error)

AR says a track is not accurate when other tracks are accurate with a confidence >1
Could be a different pressing, more likely the track is not accurate; especially if T&C CRCs don't match or quality in secure mode is <100% for the read extraction (and the re-reads occurred somewhere besides the very end of the track). Confidences given for tracks that are not accurate are meaningless when the database contains more than one pressing (and you can't be sure how many pressings there are). If there is more than one pressing AR doesn't know which CRC to display when it can't find a match. I go by the confidences of the tracks that were ripped accurately while noting that it is possible for people to submit data from the same disc on more than one occasion. The greater the confidence of the good tracks, the more likely I am to believe the others weren't ripped correctly.

AR says all the tracks are not accurate
It's a different pressing; especially if T&C CRCs match or quality in secure mode is 100% or re-reads only occurred at the end of a track.
