same CRC, not accurate, 20 days later accurate - ?

[Oliver]

Hi, I ripped a CD on 1st June and got (for Track1):
---------------------
Copy CRC 47108A7A
Cannot be verified as accurate (confidence 2) [C315538D], AccurateRip returned [543FFFE6]
---------------------
I ripped the same CD 20 days later (same settings) and got (for Track1):
---------------------
Copy CRC 47108A7A
Accurately ripped (confidence 2) [C315538D]
---------------------
This phenomenon with all other Tracks too.
How can I understand this?

Re: same CRC, not accurate, 20 days later accurate - ?

There is no issue then, previously your pressing was not in AccurateRip, a few weeks later it is in AccurateRip and can verify.

What is another pressing?
A re-release of an Album with changes?

everytime a pressing plant makes a new batch of CDs, they can be a different "pressing"....not necessarily a new version of an album, just a batch of CDs made at a different time (or even a different plant).
