I have seen a number of big graphs between 100 and 105 digits with this problem. All of the small graphs seem OK.

What is the significance of sequence 7980424322874?

I added ~90 iterations to this sequence while running it up to 104 digits. It did not fix the big graph. I did drop the 2*3 driver so it's just moving up and down between 103 and 104 digits now with a 2^n guide and no 3. I'm not willing to fiddle with it anymore. Perhaps someone wants to take it further. A downdriver might be around the corner. :-)

My guess is that it would have to hit 105 digits to fix the big graph since that would add an additional "line" to the graph.
