Appendix Table 1. Depiction of how the coefficient of variation (CV) is calculated for four 15-second epochs for the refined 2-regression model. Each 15-second epoch and the three adjacent 15-sec epochs were examined in the following manner: 15-sec epoch of interest and 1) the three 15-sec epochs before, 2) the two 15-sec epochs before and one 15-sec epoch after, 3) the one 15-sec epochs before and two 15-sec epochs after, and 4) the three 15-sec epochs that followed.

CV = standard deviation ÷ mean * 100; For demonstration, the same data is used in all appendix tables and the 15 second epoch at 8:01:15 is used as a common reference point in all tables and the data used to calculate the CV for the epoch is boxed in. The CV is calculated for each 15 second epoch and the surrounding three 15 second epochs and the lowest CV from each calculation is used for that 15 second epoch.
