I have no problems tracking net carbs personally. MyNetDiary does it all for me and my NC+P total is sent to my Apple Watch real time. It’s just one number I need to look at . I just usually select my recipe from MyNetDiary… make the single entry and look at my Apple Watch NCP value. Once it gets near 100 I am very careful not to exceed say 107 for the day.
I would go by just how I feel and not count macronutrients but I tried that and it doesn’t work. I am so heavily insulin resistant and a raging diabetic, things get out of hand quickly. If I track it closely, no hunger and good blood glucose control as well as weight loss. So I can’t just go by the typical advice given by atkins, moore & phinney/volek to eat to satiety. Have to count it.
