Fields, channels, and dwell time create two checked ledgers. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Small schedules expose few captures
Fields 2, channels 1, and dwell 5 s give captures 2 and total time 10 s.
2⋅1=2,t=10s
More channels multiply captures without changing dwell
Fields 4, channels 3, and dwell 5 s give captures 12 and total time 20 s.
4⋅3=12,t=20s
Short dwell can still have many captures
Fields 6, channels 4, and dwell 2 s give captures 24 and total time 12 s.
