I used to do all mine by hand in my head with pretty much the method that he uses in your video. It just saves me a lot of time to use my excel sheet. I’m hardly ever in the field and I am usually just sitting in my office pinning. We are strictly commercial locks (unless a friend wonders in) so needing to make a quick schedule in the field is hardly needed. I still run the math sometimes just to keep sharp with it.
Sometimes when I stamp a "0" I turn the stamp upside-down.
