You are correct. If pressure foot is up you can twiddle the tension knob all day long and all you will do is wack it out when you do put the foot down. The reason is that there is a spring in the tension activated by the pressure foot lever. I’m sure Tammi would have a better explanation. You need to take apart and reassemble a tension to fully understand why that works.
