Late work policies like this can be a logistical nightmare at scale. Rather than play the penalty-over-time game, have hard deadlines that are inflexible. Students don't have to engage in mental gymnastics with their scores and instructors don't need to track this stuff.
My view is this: a student can turn in an incomplete assignment. Work they completed get evaluated and graded. Anything not completed gets zero credit. Homework should be an investment in effort over time anyway. Unfortunately, procrastination is a deeply rooted problem that usually kills this.
