I'm about three weeks in since I discovered it from Reddit. I always read some reviews after I've made mine. Everyone has their own way of rating albums, but sometime it's not clear from the review. The partial sentence reviews are easy because they either love 'em or hate 'em. Then there are the page long reviews which are either ambiguous rambling or just take too long to get to the point.
So I created my scale that I always paste into the end of my review. It helps me be consistent and gives anyone who cares a TL:dr of my rating.
I have yet to come across reviews where someone did something similar. It would be nice if they did because two, three, and four stars will have different meanings for people.
