Method used changes caffeine extraction heavily.  Swiss Water Process and Mountain Water Process methods (same process, different companies) guarantee 99.9% caffeine removal.

I think it depends on the method used to remove the caffeine.

In contrast, your average dark chocolate bar sees [12 mg of caffeine per serving](https://www.google.com/search?q=caffeine%20chocolate&rlz=1C1CHFX_enUS425US425&oq=caffeine%20chocolate&aqs=chrome..69i57.4196j0j4&sourceid=chrome&es_sm=0&ie=UTF-8).
