We usually try to, and again, its subjective, adhere to this guide, courtesy of ReclinerMan and available in our FAQ:
5 stars: Near-Perfect Proper Recording; could be released as a proper live album (it may have already).
4.5 stars: Good Proper Recording; recording sounds great, but doesn't properly represent event i.e. improper mix/incomplete soundboard (poor audience to band ratio/one sided to a certain performer).
4 stars: Excellent Audience Recording; top-tier recording of the show from the crowd with all elements clear and audible, as it should be.
3.5 stars: Great Audience Recording; quality recording of the show from the crowd but minor problems start occurring (screaming or talking/shifts in quality/age or poor handling).
3 stars: Good Audience Recording; fine recording of the show but the minor problems begin occurring more frequently.
2.5 stars: Average Audience Recording; the performance is there but major problems begin popping up (too much screaming or talking/unwieldy shifts in quality/source damage beyond repair).
2 stars: Fair Audience Recording; no performance just problems with the source.
1.5 stars: Poor Audience Recording; you were standing outside the performance area, weren't you?
1 star: Abysmal Audience Recording; mind as well be two hours of you babbling your finger against your lips.
