That doesn't really answer the question. "it would actually double the amount of care". It would double the amount of staff hours. How those staff hours are used is a measure of patient care and not all hours are equally relevant to the patient.
As an example, if we assume you are a software engineer and you double your work hours, will you double your code output? Probably not, just like it's not a 1:1 translation of nurse hours to patient care.
