The real goal of this thread was to find if the Excelsior might be a different size than what has been established, as it affects me going forward with my TM project.The preponderance of evidence may simply make it easier to keep the ship at 467 meters.
I'm going to try scaling the Jein model as best I can and see what I come up with. I'm hoping Mr. Jein used a "corrected" bridge dome size on the model, much as he corrected the window rows to better fit a 467 meter size.
I still think it works a little bit better at one of the larger proposed scales, somewhere upwards of 500 meters or more. My current unsolicited opinion is that it works better at that size and the lower "conservative" scale is at least partially a reaction to nerd rage "How could they build something that much bigger than the Enterprise?!" from the fans.
