So when I see a table comparing the amounts of caffeine in various beverages, does that mean tea is a bigger hit than the chart suggests because it's got theophylline in addition to the caffeine listed, or do they add 'em together and report the sum under the caffeine heading? (Either way of tallying it makes sense, depending on exactly what question the folks who made the chart thought they were answering.)

Hmm. Time for more fun with or more swearing at Google. (Depending on how long it takes me to find the right search phrase.)
