 Since the operation is scheduled, we must include the additional startup delay associated with scheduled operations for the current radio mode.
-This delay is represented by the value :c:member:`nrf_modem_dect_phy_latency_info.scheduled_operation_startup`, which refers to as ``sched_startup``.
+Let ``sched_startup`` be the value of this delay, as indicated by :c:member:`nrf_modem_dect_phy_latency_info.scheduled_operation_startup`.
 
 The earliest start time of the operation is then calculated by adding both the initial startup delay and the scheduled startup delay to the current modem time,
 expressed as: ``t + startup + sched_startup``.
 
 The earliest time at which the operation can be scheduled after another one must include the additional delay associated with transitioning from one scheduled operation to the next, according to the current radio mode.
-This delay is represented by the value :c:member:`nrf_modem_dect_phy_latency_info.scheduled_operation_transition`, which refers to as ``sched_transition``.
+Let ``sched_transition`` be the value of this delay, as indicated by :c:member:`nrf_modem_dect_phy_latency_info.scheduled_operation_transition`.
 
 In conclusion, the start time of the operation being scheduled must be at least as large as the minimum between ``t + startup + sched_startup`` and ``start_time_op1 + duration_op1 + sched_transition``.
