Like I said this is my best guesstimate. I have cheated to make the circles fit. The eccentricity on the circle is as close to 0, or the aspect as close to 1 as possible. To change the ratios in the Fib circles, click on format and go to the circle ratio you want to adjust, but instead of clicking out of "format", click on the ratio NEXT to the ratio you are working on and the circle will draw. That way you can fine tune it. In the end I lock the scale when everything looks right so I can zoom in and out.
