The entire quote from my article that you have highlighted is a direct word for word quote from Griffith. That is why I said this is what Griffith says, and put the whole thing in quotation marks, with a footnote at the end. I added it before I read Berriman, and I said so in my response to Lee a couple of weeks ago. Griffith's 1892 and 1893 articles are both freely available on line and the links to both articles are above. I might add that in his 1893 article, which is where that quote comes from, Griffith generally credits Petrie for his comment. He says that he corresponded with Petrie about his 1892 article and Petrie made suggestions that led to some of his comments in the 1893 article. I know he got this from Petrie because of the Petrie quote from 1883, that is the third paragraph of my article. The reason I added the quote from Griffith is because Petrie is saying it in a sort of round about way and it seemed to me, from some of the comments I was getting about the article, that it was not getting through. I think taking the digit out beyond 3 decimal places or discussing the small differences between 99/70, 140/99 and sq rt 2 is unnecessary for my article.
The reason that I mention the 24/25 ratio is because, in combination with the 25/24 ratio of the 625 foot roman stadium and the 600 foot Greek stadium it makes both of the stadiums the same length, and both of them earth commensurate, and both of them commensurate with the remen, both in their base lengths and in their stadium lengths.
