I've found that the Daniels formula estimates much higher IBUs for a given amount of alpha acid units than Tinseth. I've been using Tinseth for a while, and found that the estimated IBUs seem quite short. When I run the same numbers through the Daniels formula, they seem a little more accurate (for my process anyway). Sometimes there is a difference of up to 7 or 8 IBUs between the two.
