The mypy project itself -- ~100k+ lines of Python -- achieved a 4x end-to-end speedup by compiling with mypyc. The official docs say "1.5x to 5x" for existing annotated code, "5x to 10x" for code tuned for compilation. The spectral-norm result (14x) lands above that range because the inner loop is pure arithmetic that mypyc compiles directly to C. On our dict-heavy JSON pipeline, mypyc hit 2.3x on pre-parsed dicts -- closer to the expected floor.
