Is it the Retul System that gives you a report and a DVD to take with you so you can use the base line data in the future? This would be handy for any changes due to improved fitness and positional changes to me. I took out several millimeters of stem spacers a few months after I got the bike because I could easily move lower in the drops and for that fact any position o the bars. Fortunately things worked for me with just the spacers being removed, no seat height or fore/aft adjustment was necessary to stay comfortable in my riding positions.
