Tea Ratings not calculated properly in JS
A tea was rated 90/100 by 10 people. After rating it about 95, the rating went down to 87. When I refreshed the page, however, it went up to 91 (as it should have). Probably just a JavaScript calculation error.

I have been wondering how the top rated teas are figured. It seems odd that a tea with only 9 ratings would come in right behind one with 94. The other day I looked at it and the top were all shifted around from where they had been and later were back, similar to the error you saw.

Steepster uses a Bayesian Algorithm to determine aggregate ratings.
