First post: Perhaps it’s something to do with the computer you’re using? Anyways, I honestly don’t really like calculating by hand anyways; I typically prefer using an excel sheet. There’s a link to one in here (in green titled “Interactive Guaranteed Analysis Calculator”) just keep in mind you’ll probably want way more than 15 ingredients in a homemade diet, so you may need to make your own excel sheet.

2. (Let me check the article there...not sure what you’re getting at)
3. Many food databases list the nutritional content of foods. I’m currently using the USDA’s database and I really like it; it’s not super in depth but it’s enough to get the GA out of.

Not sure what the regulations are in your country, but at least in the US the nutritional label on the back of food packages also has this information. Just be sure to use the grams per serving and not the daily value %.
Edit: still can’t find where it says 667...which subsection was it in?
