Box plots for the six clusters showing the cumulative probability to obtain at least one same sheet with respect to the neighbourhood function;+are outliers.

<p>Bootstrapped (<i>n</i> = 8) ‘uniform experimental data’ based on the original distribution (thick black lines) benchmarked against uniform distributions (<i>n</i> = 8) with the length of each cluster the same as the experimental data: <b>A</b> Small Set (<i>N</i> = 505) and <b>B</b> Large Set (<i>N</i> = 1417); and with identical cluster length for each set: <b>C</b> Small Set (<i>N = </i>360) and <b>D</b> Large Set (<i>N = </i>506).
