The Standard Deviations in Repeated Traces for Four Randomly Chosen Subjects Are Compared with the Average

To do this, for each ten-frame interval, the standard deviation of points is computed. Using these data the average standard deviation of these data is computed. Next, the individual variances are correlated with this average. Four colors signify four random subjects. The high R values indicate that subjects' variances, which indicate their co-contractions, are co-varying. All the R values for the four markers computed for all nine curves show positive correlations (see also Table S3).
