However, under your scenario, if I did want to allow air in via the right vent IN ADDITION TO the Guru adapter tube (to shorten time to target temp for instance), I would not be able to do that or I would have to remove the adapter. Correct?
Yes, you would not be able to introduce more air from your right vent. However, the left vent is available and will provide more than enough airflow if you want it.
