You have a different definition of "typical" than I do. I often purchase US miles at under 2 CPM during various promos. I've never seen AA miles under 2 CPM through purchase through AA (there have been times where I've effectively bought at less than 1 CPM, though, but those were things like getting Wyndham points for cheap and laundering them as airline miles). US often has 100% bonus promos during the years I've been involved in that program, and their miles are almost always cheaper to outright buy than AA's.
