Old Beer Rating Formula

I'm reviewing my first beer under the new rating system but, since I'm so dependent on the category scores breakdown figuring out what the score is for me, I don't know what score to give the beer. I'm having trouble finding the page that gives the percentage ratios for each category. I remember Appearance is 5% and Overall is 20% but I can't remember the rest and, even if I did, I don't know how to calculate the score anyway. Can someone tell me what the (now) old formula is for rating a beer? I just want to be consistent with reviews I've made in the past and this new system makes me feel lost because I have to conjure up a number out of thin air. Thanks in advance.
