They do still report Hot AC, yes.
While their top 20 does contain those titles, yes, they do seem to be playing cuts that have run their course at CHR. They're playing Rihanna, but it's Don't Stop The Music, not Take A Bow...they're playing Flo Rida, but it's Low, not anything newer.
I could see the Adult CHR distinction. But they aren't playing many (any?) currents in the format...their hottest CHR-like songs are all recurrents.
