The current setup of the Whiskybase rating is a fairly simple calculation.
We remove the top rating and the bottom rating and divide the total amount by the amount of ratings.
For instance there are 5 ratings: 90 - 89 - 89 - 88 - 87.
We remove the top rating and bottom rating leaving us with: 89 - 89 - 88 = 266 / 3 = 88,66
The top rating or bottom rating is always the full amount of top/bottom ratings.
For example: 90 - 90 - 89 - 88 - 88
We have 1 rating to be used in the calculation.
If the amount of ratings is below 4 in total we use all the ratings. That includes the top and bottom rating.
Important to know:
- Private ratings are not calculated into the average rating
- Average ratings are updated each time a rating is given to a bottle.
- We remove users and all their ratings if we find proof that this particular user has been giving false ratings.
