"Top Raters" incorrect

The “Top Raters” listings shown when listing a brewery’s products seem to have gone wrong, and are not listing in correct order (and maybe missing some users ?). Two examples

Tatton Brewery (ratebeer.com)
Four Priests Brewery (ratebeer.com)

been going on for a couple of years

don’t let it upset you cos you’re involved

I don’t think it ever misses users … just has no order to the top 6
