So no, ENY isn't firepower.. ENY is the whole package, and the whole package's lethality is the product of package's firepower and mobility. A B25H in MA A2A isn't particularily lethal because its ability to kill is very handicapped by its lack of mobility -- to make the guns' lethality useful. The american bald eagle isn't lethal to mosquitoes. Semantics like you said 
So what your saying Moot, is that the AH team adds up some kind of point value that combines Speed, range, firepower, manueverability, etc and that determines ENY {plane to plane}, But compiled MA data such as K/D etc, might support or contradict the AH point system, but is not used to calculate it.
I agree with ACK that 'effectiveness' sounds like it should be results based, and NOT spec-sheet based.
Which brings us to whether the data from arena's supports the ENY model.
Can anyone from HTC set the record straight?
My appologies for not knowing who here works for HTC.
