Hi Beth, I can sympathize about starting a new pen when you don't have to! I wish I could offer some insight into Attie's numbers, but I must say that trying to figure out his spreadsheet is challenging. So I'll leave it to you (and the experts). Anyway, I hope that your weekend will be good and that Attie's bg numbers will get straightened out to your satisfaction.
Chin up!
