I have a feeling it depends on the CBP team attitude on the day, maybe due to the fact that MIA is quite a "sensitive" point of entry. Some days, you queue with your receipt and they just take it from you, other times everyone seems to get a comprehensive interview at exit.
In fact, CBP publish wait times at immigration and when you look it shows that depending on entry point (there are three at MIA), day, and time, things can easily vary between 15 minutes and over 3 hours!
