The first part is from -0.25 to 0.75, and has a length of 1.00. The next part is from 0.75 to 1.25, and has a length of 0.50. Now that is far from the Feigenbaumvalue, but the exact value springs up when you compare two parts as far right as possible, as long as x follows a periodic orbit. The relationship at right in the table should converge to the feigenbaumvalue when you look at late bifurcations. It is important to remember that by every bifurcation, one has to compute more and more iterations before an accurate value can be obtained.
X needs more iterations to stabilize.
This is more important as you show a smaller and smaller portion of the full tree. It should be noted that the last value, 4.536 probably is erranous, because it should be bigger than the previous value. I will check these values more accurately as I get to it. Last updated 191197.
