Actually it looks like it's even more confusing. A standard 8 oz coffee is not sold at Starbucks. Their smallest is 12 oz, 1.5 cups of coffee. Grande is 16 oz., which is medium in Starbucks terms, and 2 coffees. Venti is 20 oz, which is 2.5 coffees. Adjust math and terms appropriately.

### REPLY:
Excellent catch you are correct that it is “Tall” and not “Large”.  
  
 Where are you getting your definition of a standard cup of coffee being 8 ounces? According to stack exchange it’s actually 6 ounces but realistically nobody drinks such small amounts of coffee. 
  
 I love this analysis by the way, I love dorking out about specifics as my speciality is analytics. Hopefully you aren’t frustrated.
