All of these arguments stem from The reality that CBPP is a relatively new engineering and most of the arguments are based on idea as opposed to empirical proof. As the amount of installations grows, and as A growing number of CBPPs achieve a service existence into double figures, it's rather most likely that these arguments will likely be settled As well as in ten years or so we can have a 'standardised' set up recommendation.
