Different masterings = different disc IDs?

If several disc IDs are stored for one release, it is more likely that different releases were mixed up.

Yes and why there are so many releases like is because of how we used to store releases, before NGS:

@jesus2099

Pre-NGS, there was no release groups, only releases.
All editions with same tracklist were forming a single release with several release events (one per edition).
A release event was: one date, one country, one label, one catalogue number, one barcode.
So, different Disc ID for all those editions were added to this unique release.

Then the migration to NGS (current database model) had no other choice than to split one release per release event and to attach all Disc ID to them.
