Please review the IM2 of 4.4.5 Instance Models section of the SRS, how is this linear regression reliable and how possible would it change in the future?

This model demonstrated a correlation coefficient of 0.76. Considering the probable errors in the measurement of all three factors, the determination factor is considered to be remarkably good. It is likely that the regression could be improved substantially if the composite chloride profiles were to be based on a much larger sampling of each deck, and if snowfall and traffic data for the actual years of service could be used.
