 Again, as for `recordTable()`, we provide an argument, `deltaTimeComparedTo`, to further control how independence between records is assessed. Setting it to `“lastRecord”` returns only records taken `minDeltaTime` minutes after the last record, i.e. `minDeltaTime` minutes after `timestamp` of the last recorded media file. Example with  `minDeltaTime = 60` (1 hour):
 
 ```{r example_lastRecord}
-get_record_table(mica, 
-                 minDeltaTime = 60, 
+mica_dependent <- mica
+mica_dependent$data$observations[4,"timestamp"] <- lubridate::as_datetime("2020-07-29 05:55:00")
+get_record_table(mica_dependent, 
+                 minDeltaTime = 10, 
                  deltaTimeComparedTo = "lastRecord")
 ```
 
 Setting `deltaTimeComparedTo` to `“lastIndependentRecord”` returns only records taken `minDeltaTime` minutes after the last independent record, i.e. `minDeltaTime` minutes after `timestamp` of the last observation. Example with  `minDeltaTime = 60` (1 hour):
 
 ```{r example_lastIndependentRecord}
-get_record_table(mica, 
-                 minDeltaTime = 60, 
+get_record_table(mica_dependent, 
+                 minDeltaTime = 10, 
                  deltaTimeComparedTo = "lastIndependentRecord")
 ```
