gz9 is gzip -9.  broN is bro with -q N.  Brotli defaults to --quality 11 (the maximum), which is a fun reference to Spinal Tap, but is highly unintuitive compared to every other compression program which only goes up to 9.  And brotli has no manpage or usage documentation (true to Google style) to find this out.  bro-w24 is bro -w 24.
