Applied to RoboPol monitoring data, the method identified 48 rotations across 25 sources, including multiple events in RBPLJ2232+1143, RBPLJ1751+0939, RBPLJ1800+7828, and RBPLJ2253+1608. The rotations span amplitudes from 90.8$^\\circ$ to 359.7$^\\circ$, durations between 7.0 and 111.3 days, and rotation rates averaging 5.0$^\\circ$/day.
