4dogs,
V1/Vr=1.00 is not at all unusual and is just as valid a V1 as a lower ratio (as permitted in the AFM) ... nothing "unreal" about the higher V1.
Your comment regarding being airborne before reaching the "real" V1 is, I suggest, not quite on the mark - the aircraft will be airborne sometime after passing Vr, regardless of whether V1/Vr=1.00 or 0.90 or whatever.
In the case of a longer runway with a smaller aircraft of course the operation might practicably be terminated from a speed in excess of the scheduled V1 or, for that matter the scheduled Vr on a very long runway, but this is not addressed for all the usual reasons ...
Normally V1/Vr is pushed to 1.00 in a case where the first segment performance is a nuisance and/or to address the case of close in first or second segment obstacles.
So far as enhancing the airborne phase goes, perhaps you might expand on your thoughts here as the comments confuse me somewhat....? In my limited view of the world, the after rotation performance relates principally to V2.
