How fare can AccurateRip distinguish between different users?

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?
???????????

Spoon can confirm, but I've read before that the confidence of "1" could very well be your own submission to the database.  On the other issue, I recall that the database is not updated on a "live" basis. So it likely takes much longer than a week before your submission becomes part of the database.

Well, to answer one of your questions, I'm pretty sure that new submissions are only entered into the database periodically, so the same confidence two weeks straight is not unusual.

For the rest, I think I remember that while there is only one submission for a track, the system remembers the user that submitted it, but as soon as there are two that match from different users, it simply keeps a count.

Edit: garym got there first.

hmmm, if this is true then I'm probably wrong about the match of "1" a year later. This issue has been discussed in some threads either here or at illustrate (dbpa) forum. But with a quick search I can't find them.

If there are no other results in the database for a given disc ID the a single submission is all that is required, this could easily be yourself 1 year ago.

English is sometimes not easy for me.

OK so I can gather here a --NO-- it can not distinguish, and puts eyerything in the pool, also when a user rips a CD 5 times!  What of course usally will not happen!


So its a fact that the Database cannot distinguish/differ different submissions.
When spoon, really has inventetd the DB, he´ll be able to tell that it is like this.
Or?

The database tracks your submissions, so all old submissions are replaced by newer ones.

The final database does not indicate it was your rip or not

So internally every checksum has a unique ID!
But the DB does not give that information to me.
When ist was me one year ago - I get confidence 1 now, without any possibility to know that this 1 is my own result of the past, right

This is correct.


So does the database internally recognize, that it is the same user and configuration? No.
To be able to really distinguish between different Rips, and to work perfectly, the database would have to store the complete hardware and software configuration of each user according to the CD-ID.
And thats to much data.
Is it like that?

So ridiculously, I could rip a CD in intervals of one month (so that there´s time to save my checksum).
Then, when I rip the CD after 1 year, I´d get confidence 12. And that´s all my own results!

I thought spoon said that if you reripped on same machine, when this was reported to Accuraterip it would REPLACE your old report. So if you reripped 12 times, it would still only be in the database as ONE report. So after a year if you did a comparison, you'd get a confidence of ONE.  But Spoon will need to confirm if I'm interpreting what he said correctly.

p.s. If you ripped 12 times on 12 different machines, I'm assuming that it would show up as 12 different submissions to AR. But this makes sense as the rip was on DIFFERENT machines.

Then the database must have information about my machine and my software!
Either the AcurateRip-system takes every rip to the database, no matter of whom it came from - Or it is able to distinguish.
I haven´t understand what spoon meant with his sentence

The database tracks my submissions, but the "final database" does not indicate it was me or not.
Me as a german speaker does not really understand this sentence...
Does it distinguish or does it not...

Think of it as a two-part database. The first part is where the ripping program sends the data. This part tracks your submissions and determines whether or not to add to or replace the data in the second part (the 'final' database). You access only the information in second part (the 'final' database) to verify your rip. This part does not have information about your machine.

There's one CD I ripped awhile ago (May, specifically) on two computers and submitted results on both to try to get it in the database. Now I just got a new computer, ripped the CD again, and it still says it's not present in the database. Not sure what to do about that.

Earnest question: why would you feel the need to make multiple rip submissions of the same disc to the AR database?

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.
