Does anyone understand what the difference is between the score and the raw score?  They are all the same, but it seems to me that they should be different.

It's like this:

(First, the ranking is the standard ranking automatically generated by itch.io and includes games that received less than 20 ratings. Keep that in mind.)

if your number of ratings is below the median your score is:

 raw * sqrt(ratings / median)

In that case you notice a difference.

if your number of ratings is above the median your score is equal to the raw score.

Equal to median does not really matter, both rules will give the same reusult.

The median is 7, so whoever got at least 7 ratings will have score = raw score. To see the difference check the last pages.

Ok that makes sense!  Thanks so much for clarifying that!
