You can't include Z3 in the overall calculation of that recipe cuz you can only get her with German Ship FS. If you wanna include her, you'll need to do another percentage graph or however you wanna record it.

There is a series of Submarine Exped Quest that gives you Z1 as a reward. With Z1, a German Ship as ur FS, you can craft other German Ships like Z3 and Bismarck. That said, it is highly likely that you can craft Z3 with I-8 only after you complete the Z1 quest.
