I wouldn't call it torture, but I would call it "uncomfortable". I'm average build too; I don't mind the lack of legroom in economy, but when I have to spend an entire 12 hour flight managing where my elbows are (ahead of my seatmate, behind my seatmate, arms across my chest, hold the seat in front of me, etc) it's very uncomfortable. A shared 3" wide armrest is just NEVER going to work. If I could just sit in a relaxed pose I'd be thrilled.
