Care to elaborate? In medicine, just like almost everything else, you will find a &quot;standard&quot; for each type of procedure.  Do they sometimes take more or less time?  Yep, but that all plays into the standard over time.  So when you have an outlier of the standard you can evaluate what went wrong or what was different to better understand the variables that play into these elements of variance.  Medicine is a science. The more we treat it that way the better... you cannot just throw your hands up and deem it ridiculous.
