Again, the resolution is 10000x1200 and it should be downloaded
and viewed off-line.
There is a clear upward, seemingly linear trend and this will
undoubtedly continue to infinity.
The educational system only describes repeating decimals
briefly because an in-depth analysis is beyond its resources.
But now we have CAS and we can examine repeating decimals
with ease.
Maxima can calculate this series up to a billion or more,
but it would take some time. I need to check out Pari,
which is a C program, and thus much faster:

The relevant Pari function would be znorder(x, {o}):
