Ok, But more parts, means each part is smaller in leaf count. Hence
it should be easier for a CAS to solve, I would have thought. So
in this case, the more parts, the better. One pay extra waiting
time for easier to solve pieces. At least that is what I expected to
happen ;)

Will try again and see what I can do.
