How fare can AccurateRip distinguish between different users? Options

[OliP]

I have a lot of rare CDs, with often no DB entrys, so that I cannot verify.
(I rip with EAC)

In some cases, I´ve ripped a rare CD 1 year ago. At that time it was not present in AR Database.
Now 1 year later I´ve ripped the CD again with the same Hardware and Software and configuration. Only a newer version of EAC!
- And got a confidence of one.
Cos the CD is very seldom, it´s most likely that this is my own result!
How can I know?
How far does the Database distinguish between different CD-ripping results / hardware-software configurations of different users?


I ask that, cos in the past I´ve often ripped a well known CD, got e.g. confidence 8, submitted to AccurateRip, and ripped again one week later.
Got again confidence 8! So in that case, the database has not given me my own result back that I have submitted one week ago? Otherwise I would have gotten a confidence of 9!

So whats true now?
Does AR DB recognize me or not? Remembers me again one week later, but forgot me after one year?
???????????

My old drive sucked so I ripped it on another computer to check if the rip was all good (had to use foobar's bit-compare to verify since it didn't get in the database). Then I got a new drive along with the new computer and ripped it again to see the CD was added and if it matched.
