Hi clearthinker thanks for responding. Yes having a 0-5 scale is slighly compressed but only because many recordings fall in a very narrow window of sound quality(3.8-4,4) which gives 1/10 a point great significance. Unacceptable is 3.9 or < as was posted. Theoretically a record could rate a 1 but being an audiophile more then a collector my scale is biased towards audiophiles. A poor sounding damaged record would never be in my collection or many others. The lowest rated record(non damaged} so far has been 3.4 due only for sound quality. On the other end of the spectrum two recordings so far have received a 4,8 a Sheffield Labs/Harry James LAB 11 and a Mercury/Balalaika SR 90310. I do agree with you that nothing can be a 10 or 5(my scale) but I could run across a 4.9 I have played(graded) about 45% of my vinyl collection which contains around 1400 albums. In conclusion I do place more value between 4-5 on my scale because that is where a majority of modern vinyl resides, so yes its skewed but not misleading.
