Fictional example data. - Likely cuts (C01, C02, C04, C08): 8.1 s. Raw 108 s becomes about 99.9 s. - Check-first rows (C03, C05, C07, C10, C11, C12): 20.8 s. Cutting all of them as well would give about 79.1 s, but C07 and C10 are probably demonstrations. - Kept: C06 (deliberate repetition, 1.5 s). C09 is inside C08.
