(1) A is half again as B
(2) A is as much again as B
(3) A is half as much again as B
I heard (2) and (3) sounded wrong to an American ear, with (1) only sounding right. How do you see it?
I think - half again as much as B.
(2 sounds likes 2x as much, not 1.5x)
No, it was intentional.
Half as much again sounds okay, but half again as much sounds more natural... to my American ears.
But honestly, I don't hear it very often at all.
