M&R deferred to Petrie on several occasions.
229.92" is not, repeat not, the height of the KC walls.
Then, M&R’s measurement is a mean figure +/- 1” or thereabouts.

Suffice to say, I am well aware of the top course difference, but I didn’t see it necessary to involve it in my calculations - what's 0.215" between folk . . .
Anyway, do you now see how some folk come to see the pi ratio in the north and south walls of the KC?
