*waits for the gasp of shock* 
I feel I should point out the caveat that I’m on steroids on the moment, and most of the swing I have is to deal with the massive peak of insulin resistance I get in the afternoon when they kick in. Before I started on the steroids my basals ranged from about 1.1 U/hr to 1.9 U/hr. I know other people who have a massive rise in the morning to cope with dawn phenomenon. My diabetes clinic are very much of the opinion that whatever level of insulin you need to keep your BG in range is what’s right for you, and everyone is different.
