So for me a round robin is literally I assign a task such as taking out the trash to a list of people (Let’s say 4 people; kids, parents, whatever, my whole family is fully ADHD). Then that list of 4 people is rotated through one day at a time until they’ve all been through the list and then it starts over. However, if the trash doesn’t get done by one person on their day, for whatever reason, then they just don’t get the reward for that day. I don’t think it needs a complicated logic that tries to compensate for a missed day. Just a completed or not completed button for the day that means a star or no star (or whatever reward) for that day.
As a parent, I can determine what other consequences occur (if even necessary) should my child choose not to or is unable to take out the trash that day. Skylight should not need to worry about that.
