How much people happen to eat in one sitting is nice bonus info, but it doesn't make sense to complain that the data has been normalized into density figures.
Either way, a little 16oz carton of Ben and Jerry's that people smash in one sitting is 1200 calories. So it's still more sugar- and calorie-dense than boba tea.
I don't really see the point in bickering over calorie-dense junk foods though. Both of them are displacing healthier foods in your diet that you could've eaten instead. Neither should account for more than a small fraction of your calorie intake.
