Personally, my personality doesn't take too well to being hounded, so I don't want to have more than 5-8 things open at a time, in total, from anyone . . . . but in asking their question, they assume that all of the orders in your queue are their orders; when in reality, the Orders are actually from all over the place. So it's kind of a silly type of egocentric ("Mill Centric") question which assumes that you are their slave and their slave alone. They couldn't care less about what that total number of Orders is that you can juggle . . . . just their's !
So an answer might be "I can handle 20 Orders Total; but no more than 5 from any single Source." You won't be able to give an answer like that.
