Comment 20 for bug 1315552

I believe that "less-good copies could be included below more-good ones from the same call number and library, but above succeeding copies that are better but are on other call numbers" is currently true in releases (and perhaps has always been true?). In effect (for clarity), the ranking system will guarantee you see the "best" copy first, and depending on overall availability and copy/call-number ratio, you're pretty likely to see other "good" copies as well, but no guarantees.

I'm not discounting the more subtle goal of true best-copy order, but I agree that maybe we can consider it outside of the scope of this bug? Unless the proposed branch adds new problems, my vote would be that we solve the more immediate need ("stop-gap") and consider true best-copy ranking as an enhancement on a separate bug.

Thanks, Mike!
