Investigate why witness sets aren't reproducible
...
All the random number generators seems to be seeded, so why aren't the results
reproducible?

Test a scale constraint
...
In all but a few cases (for example, a single point on a plane), we
should be able to us the radius-coradius boost symmetry to make the
average co-radius—representing the "overall scale"—roughly one.

Seek sample solutions by cutting with a hyperplane
...
The example hyperplane yields a single solution, with multiplicity six. You can
find it analytically by hand, and homotopy continuation finds it numerically.

In the cases I've tried so far, this leads to substantially smaller

modules now.
