Working the Model

When we work on a model, do we approach it at first like a thought download? Do we place our intial thought-feeling-action-result to the circumstance on paper, reflect on what was written, and then revise it?

Is the model’s primary use to help someone solve a problem? Or is it a method of evaluating a thought and whether or not it serves us?

Is it always the thought that needs to be adjusted or can your F and A lines be changed to create a different result?

My initial impression in attempting to work through the model and from recordings seems to be that one almost always needs to change the thought. Could a thought be valid and but not the feeling or actions behind it?

Thank you so much.
