You forgot to add the url for your additional source. I found this one:  which, if it's the one you meant, you might want to add. From what I see in my find and in your quote above it gives the height as 800ft/244m and NOT the 244m (801ft) that you changed the text too. I understand that 244m converts mathematically to to 800ft, but it is also true that 800ft converts mathematically to 244m. So as the latter seems a better match, and as we have no good reason to assume otherwise, I've restored the original figures so as not to deviate from the official dimensions.
