Choose if you want to be informed when the time is up or early enough, to give yourself one last chance to accomplish your task on time.
The reminder will alert you when there is 20% of the total time left. At point you should still be able to achieve 80% of your goals. Check how much time you can save modifying the duration of your daily routines.
