Ascoli's next assertion may be that Mizuno has put in a random fudge factor.RDM
BlowerPwr = [RDM ] *(1.722298 * Airspeed - 3.484167)
I'm pre-empting that.
ascoli's assertion, as I understand it, is that the stated airspeed is not measured, but in fact calculated from measured blower power and the known (see paper) blower power / air speed relationship.
This is careless presentation of results; it should be made clear that the airspeed figure is so calculated, not measured. It does not affect the results. It very slightly, not greatly, affects the credibility of the paper (any carelessness makes readers more likely to expect other carelessness).
