I'm starting a new thread from the To Low Carb or Not to Low Carb just because it is already so many pages and it's hard to navigate.
From reading your posts in that thread, it sounds as though you keep your BG daily between 65-140, have a standard of about 25, and eat moderate carbs of about net 160.
If this isn't too nosey, I'd love to know your thoughts on how you manage to do that. I can't even imagine a universe where I could do that. What kind of carbs are you eating and what's your insulin regimen?
I think that my biggest obstacle is that my short-acting insulin (Novolog, but I've also tried Humalog and Apidra) has discernible action 4 hours out. Any bolus that prevents spikes above 140 will ultimately cause a low, even with meals of about 25-35 carbs. Although my snacks are smaller than in the NPH days, I still have to snack mid-morning and mid-afternoon.
I have good A1c's (in the 5's), have the pump and Dex, limit carbs to about 100-120 per day, etc. But I am not close to obtaining the type of stability you talk about.
So Maurie, if you have time to respond, what's the magic?
