It's a weighted average:

Take each rating level 1-5:
(# of ratings) ^2 / (rating * ((# of ratings)^2))

So original example

2 ratings of 3 = 2^2 / 2^2 * 3 = 4 / 12
1 rating of 4 = 1^1 / 1^1 * 4 = 1 / 4
add up numerators and denominators and divide = 1 +4 / 12 + 16 = 5/16 = 3.125

So appears to be rounding up to 3.2. So it appears Futiles was kind of right...Only works out cause the double of 2 is the same as 2 squared.

Thanks! :cheers:
