Counted from the NTSC-U disc's own function tables; a function is final when PAL's source for the function with its code checks MATCH there (config/us/map.tsv, tools/version_map.py), and the fuzzy figure adds what the near misses and the C that does not check yet reach there (docs/versions.md). 51 levels; each distinct function counts once.
