Results of the tests for statistical significance of the presence of intervals.

Column Test 1:% significance shows the percentage of trials for which the existence of special segments was found to be statistically significant. This was determined by comparing the success in matching the empirical velocities either with the model for the combination of velocities or their approximation using the mean velocity values. The analysis was performed in the log velocity space.
Column Test 2:% significance shows the percentage of trials for which the existence of special segments was found to be statistically significant. Here the success in matching the empirical velocities achieved by the model of the combination of geometries was compared with that using the trigonometric approximation. The analysis was performed in the log velocity space.
