Hi Hermione.
From my experience Hancock has very little true understanding of the math involved at Giza and in Egypt. I will concede that the interview was painful to watch but that was because Hancock was making no sense and was, as he is apt to do simply spouting off things he has heard, West (R.I.P) and Bauval had/have a much deeper understanding of this math.
Putting that aside, the author seems to me to totally lack any background in the math involved also . A case of two wrongs making a wrong.
