My rating system

I have rated beers using a seven-glass rating system, with 7 glasses being the highest. I revised the system on March 27, 2021. The revision will reduce the average number of glasses in the ratings. I want to make 7-glasses a special achievement. The change pushes some 7s to 6s, some 6s to 5s, etc. Since I do NOT revise ratings automatically, reviews posted before March 27, 2021 still use the old rating system. I also began to give x.5 ratings for beers that are too good to be rated x but not quite good enough to be rated X+1.
