This goal has the following fine print specified by rperce:
No ratchet. Daily checklists pull from trello.com/b/GMfBhGCV, lists Monday through Weekend. Checklists can be completed up to one day ahead of time and up to two days after, e.g. on Wednesday you could complete at most Mon+Tue+Wed+Thu; on Monday, Weekend+Mon+Tue. Fractional completion counts; all tasks on a given day have equal weight.
