It's exciting to see some more aero helmet testing data, but Giro does have a valid point. The testing was completely sub par as far as scientific rigger goes. Testing one head position? Using the wrong size helmet? Not providing the raw values collected? If someone is going to all the trouble of testing and skip on basic details like that I would have to question to rest of their work. But to top it all off, their aero figures were averaged across all yaw angles? That's just poor data analysis.
