ReRe's Law of Repetition and Redundancy [5] could benefit from a refinement that accounts for the inverse relationship between width-of-delivery-window and certainty-of-delivery-date... maybe:
A programmer can accurately estimate the schedule for only the repeated and the redundant. Yet,
A programmer's job is to automate the repeated and the redundant. Thus,
A programmer delivering to an estimated or predictable schedule is...
Not doing their job (or is redundant).
