I'm a T2 on Lantus/Novolog.
Before insulin, I got the same bg control with 50 g of "net" carb as with Bernstein's diet. I tested at 25g of carb for a week, then 30, then 35... etc up until 55 where I lost control. So I stuck to 50g "net" carb for years.
I don't personally see the benefit in going lower than necessary. Having a higher-than-Bernstein limit means I can eat large servings of veggies, cottage cheese and Greek yogurt, small servings of berries and melon, half a pomegranate or apple, and small servings of barley or buckwheat.
I'm not on his diet, but mine. I consider this a Bernstein-approach in that he developed his diet via bg testing and that is how I developed mine.
I lost bg control subsequent to a pancreasitis attack and am now on insulin. While learning to dose, I quit measuring "net" and just went with total carb for simplicity's sake. My personal "rules" for Novolog are 3u if preprandial > 100, 3u if first meal of the day, 1u per 5g carb, 1u per 10g protein and 1u "correction factor" to lower by 30 mg/dL if my preprandial is high.
Using my own insulin rules, I maintain good control if breakfast < 20g carb and lunch and dinner < 40 g carb. To me, good control means fastings and preprandials of 70-110 and postprandials of 100-140 (I need a wide target goal because my IR is very variable).
If my carb intake increases beyond 20g total carb at breakfast or 40g total carb at other meals, the amount of insulin that takes me to baseline at my next preprandial won't control my postprandials and I'll spike over 140, sometimes WAY over (my body seems to think if it hits 160, might as well go over 200).
So for *me*, that's where the law of small numbers breaks down. I presume YMMV.
ETA: I do not eat 100g carb/day. I average around 60-80g/day, of which 30-40% is fiber.
The limits above are the limits I've found as the most I can eat at any particular meal, but I suspect if I pushed those limits at *every* meal, my system would break down.
