"I probably haven't done the systematic particularly well." "It's hard to think right on the spot like this." 9% (6/64) Sample interviewee quotations: "I don't know how to explain this to you to get it right." "Does that help? This is tricky."

The 9% (6/64) interviewees who did not make physical changes to the diagrams each made verbal comments reflecting edits that should be made to the diagrams.
