I must have a different version then, all I get is "confidence level"
and it's expressed as a count, i.e. the number of other people who have
gotten the same exact checksum.

If even -one- other person has gotten exactly the same, then the odds
are overwhelmingly that it's accurate, because the odds of two
identical random errors are unfathomable.

When it becomes a problem is how to interpret if you do not have the
same checksum.  If all tracks are marked "inaccurate" then most likely
I'm using a different CD pressing.  AccurateRip will point this out to
you.  As I indicated, this is very common with CDs made locally or with
imports.  If only one track is listed in error, that's a big red flag,
but only once or twice has AccurateRip reported a track in error where
EAC didn't indicate any errors.

It isn't enough when you get negative AccurateRip results, agreed. 
Still, the odds of an entire album having negative AccurateRip results
caused only by errors are quite low.  Even on heavily damaged discs you
can usually get one good track.  But yes, the odds aren't 0, so you'll
never know for sure.

True, some drives are better than others.  My laptop DVD-ROM drive
absolutely sucks at this.  It's slow and very, very sensitive to even
minor disc damage.  There are two drives in my desktop, a Pioneer
DVD-120 and an LG GCE-8523B.  I think I've used the Pioneer once or
twice, it wasn't very good.  It's also missing a few error detection
features, EAC indicated the LG drive was preferred.  So I use the LG
drive.  It's been very good.
