How does Daycast determine what tasks it shows in the autocomplete list that appears when I click the plus sign to create a new task?

This list is populated with recent and frequently-used tasks.

Tasks you’ve marked complete will not appear in this list unless you continue adding it to your day plan. For instance, if you add a task titled “Team meeting” to your day plan every Monday, Wednesday, and Friday, and you mark this task complete after the meeting ends each day, Daycast will recognize that it’s a recurring task and keep it in the pre-populated task list.
