How hot is my stove?

I search online led nowhere so I decided to create the content myself. I found a rough estimate of the temperature of the surface of a scratched teflon pan using the smoking point of two fats, butter and refined canola oil (325 and 425 respectively).

Big burner|Small burner
325 1 min | 1 min
425 2 min | 2 min

It seems the size of the flame didn't matter all that much. Also important to note, the small burner was tested second and retained heat from the first test even though it soaked in the sink with cold water in it for 2 minutes.
