how do i know what tracks to keep? audio quality.

I think for general listening, 70% and above is good. 100% is not realistic since many publishers release music that's badly clipping (so it sounds over-bassed and louder).

If you have a good audio system, and by that I mean high-end speakers and amplifier, or high-end headphones, then you'll hear a difference between 50% and 100%. But if you listen mostly in your car, or with basic earbuds, or computer speakers, you won't hear much of a difference.

So just listen to the song and decide whether it's acceptable quality to YOUR ears

It's complicated question you must understand that rating calculated from many values, some may be important for you some not. Example mono files have lower rating than stereo, but some old compositions exists only as mono and have very limited frequency range. Please read more here: http://www.similarityapp.com/analysis
In new version you can see any fields from analysis in audio duplicates results, it help distinquesh quality by any calculated field.
