Intake efficiency is directly related to camshaft choice and there's potential for tremendous differences in cams that have the same lift, duration, and LSA figures. So while I get the secretive business approach - I can't see where it might be a dangerous-to-business spec and it is critical to grasp the whole picture of the testing. When all that's posted is a result and "Same hydraulic roller cam" it's not enough information for any real discussion on the result.
