Could you just use math.pi here? These constants in general feel a little 'magic', is there a CDF function in the stdlib or numpy that could be used instead?

There is a CDF function in Scipy, with different behavior as to how the wraparound is handled. So it's both too big a dependency for this little thing, IMHO, and it doesn't do what we need anyway.
But, yes, could use math.pi.

You could use from __future__ import annotations and dispense with these typing imports by using PEP 585 types
Support for the Heirarchical Performance Testing (HPT) method in this paper: T. Chen, Y. Chen, Q. Guo, O. Temam, Y. Wu and W. Hu, "Statistical performance comparisons of computers," IEEE International Symposium on High-Performance Comp Architecture, New Orleans, LA, USA, 2012, pp. 1-12, doi: 10.1109/HPCA.2012.6169043. This is largely a direct port of the bash implementation available here: https://github.com/cirosantilli/parsec-benchmark/tree/master/toolkit/hpt This approach is a more robust way to measure overall effectiveness across a number of benchmarks. It is still biased in that the benchmarks should be a representative sample, but it accounts for the fact that some benchmarks are more reproducible and reliable than others. It has been modified so that each benchmark can have a different number of samples (the original code assumed the matrix was rectangular, but there is nothing about the method itself that should require that).
