Which is the whole point of the thread:Thuban and the Descending Passages-The Key to Dating the Pyramids?. Using Proctor's calculations Thuban would have been visible in the DP c. 3,350BC with a range of a few hundred years either which way. Your calculations say it would have been in the middle of the DP c. 3010BC. Audrey says Starry Night says Proctor is correct. The thread further goes on to show how the RCD studies are much more in line with this date on average than they are the traditional 2550BC. I know this is not what some of you want to hear, but all told I find this very interesting. Thank you for your effort on this.
