I've been 6' and 3/4" for about eleven months.. I know this, because that's what I was at the doctor, and I weekly height-measure myself against an adult friend who's too old to grow and too young to shrink (:P).
I figured I was done growing, but yesterday we measured against each other as normal, no shoes, same surface as always, etc. - I definitely tower over him a good inch higher than I used to.
Is it even physiologically possible to grow an entire inch in one week at sixteen?
