Fair common. As far as I know in some types of abuse circles? More than the multiple guys, switching up like a merry go round.But I'm a bag they fill up, a conduit?
If statistics & anecdata are your friend, just saying that isn't unheard of. (For the more statistics angle, I've gotta dig, was something in DD-NOS research out there.

No sweat with re-stating things. ;) Recaps are good for reading comprehension.
