Yeah, like Suvorov described these can't be taken without context. Scenarios are used to simulate a specific situation in a vacuum. The reduced RCS aircraft might be mandated to use a Luneberg lens, not allowed to use any number of avionics/sensory equipment, one side gets omniscient AWACS while the other gets limited-to-no datalink support, scenario starts at a merge instead of BVR, etc etc. It shouldn't be taken as representative that a given platform will smoke the other platform.
Sort of like a jet I'm a unabashed fanboi for, the JAS39 Gripen. When you're artificially fed information to feed your Meteor missile (information that none of the JAS39 operators are capable of generating in real life), it doesn't matter that your own radar has half the detection range or less of the missile's actual range...and all the sudden it looks really impressive to an outsider when in reality it's just a fixed scenario for a specific purpose.
