I had a look at this debunking video:
One of the claims in Shining Code 2.0 which I found intriguing is that room 217 in the book was changed by Kubrick to room 237 to represent the 237,000 miles distance between the Earth to the moon, even through the distance changes due to the elliptical orbit. But this guy looked at old textbooks to find earlier references that generalize the distance and hasn't found any reference to the moon being 237,000 miles from the Earth.
