HydrogenAudio

My rip(s) appear not to be getting accepted in the AR database:

Starting point

• 1 pressed retail audio CD
• 2 different PCs
• numerous different disc drives
• not present in either database on first rip (must not have been popular)

Steps taken

• EAC rip on PC1 using drive1
• EAC rip on PC1 using drive2
• EAC rip on PC2 using drive3
• EAC rip on PC2 using drive4
• [...]
• submit results on both PCs
• wait (months)
• CUETools verify

Expected outcome

• AR and CTDB confidence increases with each rip

Actual outcome

• only CTDB is incrementing (8/8 now)
• AR steadfastly disavows any knowledge of the disk ("disk not present in database")

Questions
It's been 8 months since the first rip date - is there a logical explanation for this phenomenon?
What requirements for AR am I not meeting?
Would I need to rip a different specimen of the same disc?
And if so, doesn't that mean if there's only one copy of a cd in existence (like that Wu-Tang clan one, Once Upon a Time in Shaolin), it could *never* get into AR db?
Where can I learn more about these workings of AR?
