What is the speed of good airflow in a smoker?

Hello, all!

The obvious answer to this question is whatever turns out good food, but I would like to see if it can be quantified a bit. Have you read, or do you have an anemometer and know, the mph of airflow out of the stack when you believe your smoker is drawing air efficiently? Is it 2mph? 4 mph? Just curious.

Thank you!

You should check out this video,
He had the same question. He explains airflow and used one on the stack but it didn't turn out so good because it was plastic and melted

Newglide - I watched that video a while ago and noticed he melted his rather quickly. I have one and I just hold it over the stack long enough to get a quick reading. Only takes a second or so. Since the heat coming out of it is warm, but not necessarily hot, I am not sure how his stopped working. I am hoping others have had some success maybe. Just curious as to what the airflow rates might be.
