Thanks - I'll fix it!   You're apparently the first person who actually looked at it.

To draw the diagram correctly it's also important to know which is bigger: 729/64 or the appropriate power of 2 (namely 128) time 64/729.  That's what tells us which circle to draw to the left, and which to the right!

I think I got that part right, but just drew the arrows wrong.
