I didn't write the article ... sorry. But I've seen calculations of magnitude going back into ancient times. I guess it's more a matter of do you trust the calculations, and having no further info myself, I can't say.
As an answer to your last question, you can just run both tests (plates and new tech) simultaneously on multiple stars and then calibrate and extrapolate.
