For the sake of a more definitive question, I define chores as domestic tasks that are recurring, generally unenjoyable and have no hard datelines. The conditions are such that available manpower is inelastic. Are there any productivity studies/theory that advocate a reasonable amount of time to be allocated for such activities for achieving best results? As opposed to aiming to complete individual tasks.
The motivation is that since there is no end in sight, it might be better to simply set aside a fixed fraction of available time and call it a week (day)
