When I am drinking a wine I decide if I think it is outstanding, very good to excellent, or good then I decide to what degree I agree with that description and that is how I give an 87 or 88. Sometimes I feel a wine is between 89 and 90 points and I have to deileberate a bit or sometimes a wine shows me something great then seems to pull back or it is just not as enjoyable so I will give it a range that spans two categories such as 88-91.
Is it parker or WS that describes 85-89 as very good to excellent?
I do slightly bastardize the below
95-100 Classic - totally worthless and used to elavate wine to something that it is not and make the prices outrageous.

90-94 Outstanding I like this category the way it is.
85-89 Very Good to excellent, very good 85 and 86, 87 transcending to excellent and 88-89 I feel very confident saying it is excellent.
80-84 Good, a solid well made wine. I typically like an 84 but the wines I consider 80 - 83 I should possibly be putting in the 70 - 79. I don't know, to me 84 for solid well made seems like we only need on point for that category.
75-79 Mediocre, a drinkable wine that may have flaws Do we need 9 degrees of mediocre to communicate our experience of a wine?
50-74 Not recommended.
