Three digital sensors, S_1, S_2, and S_3, log measurements on repeating intervals of 4 seconds, 6 seconds, and 9 seconds, respectively. Sensor S_1 logs at second 1 of its 4-second cycle, S_2 logs at second 1 of its 6-second cycle, and S_3 logs at second 1 of its 9-second cycle. In a 360-second logging session starting at second 1, during
