some days all some days none, clinical experience is very difficult to schedule, that is why you have some providers who are better then others at some aspect of their training, even if they went to the same program, take for instance OB if one persons rotation was routine they may not be as good as a person who followed if that person had several crash sections or more complicated patients PIH etc.
Following your logic MD residency should really be shorter after all efficiency vs antiquity eh.
