I am currently rewriting the parallel computing for the unsequa module as it was not working properly. So these changes are probably not needed. I will update at the end of today.

Actually, since #763 might take some time to review, we can also merge this pull request first.

Suggested change
| chunksize = max(min(unc_sample.n_samples // pool.ncpus, 100), 1) | |
| chunksize = min(unc_sample.n_samples // pool.ncpus + 1, 100) |
I think this is more elegant.

Hm. Maybe. But when you have 6 samples and 3 cpus the chunksize is 3 where 2 would fit better- right?
Doesn't matter I guess, but the elegance comes at a price of reduced readability imho.
