Agreed, some things have changed - many things have changed - due to trial and error. Some fails, some wins. Drawing board always evolving.
Overall, it will be better than expected, especially for my first attempt and having improper tools (borrowing tools or getting creative with the wrong tools). Working with the screen door I made, I had to start over from scratch on that one. Changed how I am screening the side window four times now. Ended up using a dremel and cutting bit to make the trench for the screen/piping.
