So, a game jam I was in just completed its ranking period, and in looking at the final ratings, I can't help but noticing the two columns:  "Score*" and "Raw Score".  The asterisk next to Score to me suggests there ought to be a footnote somewhere explaining how it was calculated, but I see no such footnote.

I'm assuming the difference between the two is something itch.io does automatically, but I'm wondering what the logic behind it is, because it doesn't seem to serve any purpose but to punish everyone who got fewer ratings than the median number.  (And yes, part of that is indeed irritation since I got fewer than the median number and thus my scores were reduced, but part of it is genuine confusion.)

How is the Score* calculated, and why?
