Thanks to the separate mention of the new features of the verifier component I was made aware of the accurate rip db and checked some of my older rips against it.
After digging into the subject some more I also compared the results of the foobar verifier component with those of cuetools, corrected offsets with cuetools, etc.
In the course of events I have stumbled across some questions.. maybe you can enlighten me?
First some logs.

As already mentioned in this thread without the knowledge of the pregap length foobar (or cuetools for that matter) seems to generate another disc id and checks that id against the accuraterip db, getting of course different results than it would get with the knowledge of the length of the pregap.
Now some questions I wonder about:
1. Is this a design flaw of accuraterip or what is the reasoning behind assigning different ids to discs with exactly the same audio data checksums except for the "digital silence" in the beginning?
2. Am I right with my assumption that the most plausible bit-perfect copy of my original CD would be the one with offsets applied (I have many very old not offset corrected rips I want to "fix" now) according to the results given by cuetools (which has the right knowledge of the pregap when a cuesheet or an EAC log is available)?
I.e.: Which one would be the perfect rip in the above mentioned case? The original rip or the one with an offset of -18 applied?
As it can only be one of the two, how comes the other ones are still flagged as accurately?
3. What is the smartest way to handle pregaps in order to conserve the possibility to create bit-perfect copies of the CDs in the future? Given that foobar is not willing to handle EACs non-compliant cuesheets due to some stricter standard enforcement rules (as older versions were able to process these non-compliant cuesheets) the only other possibility to to get accurate accuraterip (pun intended

) results with foobar would be to process the files with cuetools with gaps appended + HTOA which is not really feasible (at least for me).
Is there any other way I am missing?
How shall I handle pregaps in future rips to avoid this annoying scenario?
4. Am I even able to produce bit-perfect CD copies with my flac files and foobar without foobar able to read my old cuesheets?
Sorry for the wall of text.. but I am a bit confused
