So rather than doing "the math" we have an off the cuff generalization that says it won't scale up. Sikorsky therefore has either done an off the cuff generalization that says it is good, and they are wrongly proceeding, or they have done a rotor design that says it is good, and they are proceeding, or they have done a rotor design that says it is bad, and are proceeding anyway as a way to perpetuate the Blackhawk indefinitely.
