ITunes Match - Completing Library

Question

Is there any way to complete the library by eliminating low bit rate tracks and uploads that should have been matches?
Having resolved ineligible tracks (https://discussions.apple.com/thread/3623151) and inconsistent results (https://discussions.apple.com/thread/3629795) there are two categories of tracks that would be great to resolve, notably:
(1)  Low bit rates tracks:  These are listed in a smart play list showing all songs with a bit rate less than 256.  Many of the tracks listed can easily be found in the iTunes Store, hence they should 'match' allowing a download at 256 - how can this be achieved?
Example:
(2)  Uploaded tracks: These are listed in a smart play list showing songs with an iCloud Status of uploaded.  The majority of these tracks are also readily found in the iTunes Store, several being exact matches for entire albums but for some reason iTunes Match did not identify the match - how can this be resolved?
Example:
With these as the last two areas to resolve, iTunes Match will have successfully converted my full library.  Any suggestions very much appreciated?

Answer 1

Worth looking again at the current description of service, it reads:
"Here’s how it works: iTunes determines which songs in your collection are available in the iTunes Store. Any music with a match is automatically added to iCloud for you to listen to anytime, on any device. Since there are more than 20 million songs in the iTunes Store, chances are your music is already in iCloud. And for the few songs that aren’t, iTunes has to upload only what it can’t match. Which is much faster than starting from scratch. Once your music is in iCloud, you can stream and store it to any of your devices. Even better, all the music iTunes matches plays back from iCloud at 256-Kbps AAC DRM-free quality — even if your original copy was of lower quality."
Given this many of the requests for support are naturally focused on how to complete a reasonable matching exercise.  Currently approximately 8% of my library is not successfully matched, hence the number of files 'uploaded'.
If the service simply said 'whilst matching can never be wholly accurate we anticipate that the majority of your library should be matched provided that the songs are held in the iTunes Store' many folk would simply accept the partial matching as a feature of the service.
For as long as this is not made clear it is a source of frustration for many that apparently clear matches are not succeeding.  A further example from my only library is provided below:
Example:
Here in the first album by Phil Collins we can see all tracks are successfully matched.  In the second album many are successfully matched but 4 of 15 are uploaded.  Looking at the iTunes Store Phil Collins Serious Hits... Live! is shown as a current album.
iTunes Store entry:
The suggestion, flagged by Keith, that Apple might offer a 'force upload option' - or mine that Apple might offer a 'discretionary match option' would prove very helpful in resolving these apparent anomalies.
Having made these points it has to be said that iTunes Match overall does represent a superb service, it is simply let down by the current description which over promises.
