Order of Priority

Atomic preprocesses events before sending it to the scheduler to apply attributes to help the scheduler decide how to rearrange the schedule. Atomic gives you the freedom of multiple choices to train your events however the way you want. See Train your events for more info. However this leads to overlap and so Atomic has to prioritize what settings matter more than others

The order is in descending priority

1. Specifically trained events ie when you tap on Train on event menu options
2. Tag related default settings - See Smart Tags
3. Global settings set in Calendar Preferences
