The reporting of the information is accurate. It is well presented and shows that the image was truly analyzed and compared by the writer prior to presenting the information. There is just one small improvement that I would have made, had I written this report. I would have color coded my report based upon the colors representing the instruments. I would have done that as a part of the summary overview. Why would I use the color coding? It would have created a more imaginative information pattern for the reader, who will not have a copy of the report before them. The color coding is an integral part of the report. It would not have been included otherwise.
