What is a default quality of brotli command?

[stokito]

Nor in brotli --help nor in man brotli is not mentioned what is a default compression quality.
It just said that quality can be in range of 0-9 but later it said that -q param can be in range 0-11.

$ brotli -h
Usage: brotli [OPTION]... [FILE]...
Options:
  -#                          compression level (0-9)
  -q NUM, --quality=NUM       compression level (0-11)
  -Z, --best                  use best compression level (11) (default)

What I see from sources in brotli.c in main method:

int main(int argc, char** argv) {
  Command command;
  Context context;
  context.quality = 11;

So it looks like the default quality is 11 i.e. best.

1. Could you mention this somewhere?
2. Can we set the maximum quality by -11 param?

The default quality is mentioned:

  -Z, --best                  use best compression level (11) (default)

I think the single dash (-0 to -9) quality parameters are just for convenience, the problem is that by convention a single dash parameter can only by followed by a single character, so -10 or -11 would break the convention.

@chylex Thanks for the answer.
