i've always felt an AA table is like a timeline. You can look around that table and see where you have been and you can see where you are and you can see where you can go. the same holds true here. its not even all that chronological either. you could have someone whos still plenty wet drop that tid bit of advice you just need to hear. and someone whos been dry for decades say absolutly nothing useful to you but perhaps is plenty helpful for someone else.
