Here are the numbers. I can verify that you can hike rough terrain and read large lettering by Moonlight. This was especially true in the winter with leaves off the trees and snow on the ground reflecting the light. But I did not find this to be the case for starlight but it was most definitely not pitch black like a cave. So I hesitantly agree with you.

Note that it is possible for retinas to be able to see different levels of dim light. I have no proof of that so I am just guessing. I have an extremely rare retina disease, and it is very difficult for me to see things at night. And now during the daylight as the disease progresses.
