A “I felt comfortable administering my own test,” (B) “the test was not difficult to perform,” and (C) “I could teach others to perform these tests.” The mean responses to questions A, B and C were 6.36 +/− 1.69, 5.61 +/− 2.35, and 6.56 +/− 1.43 respectively. Nine of 50 participants did not submit responses. The 7-point heatmap scale is provided to the right of the figure
