My last one was 6.1, before that 6.0. I went through a period of a lot of adjustments to my I:C ratio a month ago, I think that’s what made it go up a bit. But hey, I’ll take it. Gonna shoot for a 5.9 next time.
Great job! Still, pretty good numbers. 
Don’t be disappointed with a 6.3%, Tony. It’s a very good reading for us T1s. In the thirty-odd years I’ve had this disease I don’t recall ever getting lower than 6.8%. She’s a tough and demanding mistress is diabetes ;-))
