I have seen many people who had surgery, with recovery either being shorter and longer than expected. "Typical" in what context?. If the typical time for something is 6 weeks, I want to know something about standard deviations. Is typical the middle third? than another third is maybe 3 weeks or less and another third is 10 weeks or more. And so on. Which is why surgeons always schedule follow up visits as every patient reacts differently.
