ALL my convention Rifles .. Not Pups run from @ 1.7" to @ 2.3" with the Pups @ 2.5" to 2.8" center of bore to center of optics. Lower the better is what i believe correct.
Check out that link very interesting read
Very familiar with all things "CANT" .... my reason is that of trajectory profile and being a "Hunter" Field target shooter ( 8 State, Gran Prix and a National championship win ) where the amount of correction be it hold over or clicks is far less with a low scope position over a high one IMO. The gains had to get a somewhat flatter profile at distance does not make the sacrifice of critical short distance correction worth it. Again to me.
Again neither is right or wrong, just understand each has advantages or disadvantages pending where one places the priority in whats required in close and out far with each height extreme used. Somewhere in the middle is a good compromise which is not such a bad idea.
