The above is of course generalized and unreferenced and not meant as a clinical white paper on the subject, to bring that to the table one will need to look on their own elsewhere. It is rather a hopefully easy to grasp quick study on the subject. I am certain however there is no intentional bias other than what the simple mathematics might conclude, in fact I personally think the numbers are quite conservative and could easily be skewed in other directions also, e.g., how many MABs average 30 mph? The differential factors represented do for me satisfy an overview that places it beyond mere hearsay or unfounded opinion.
