The valid range is hard-coded to be 0...10, as in Opus. I think this is generally easier for users to manage than the Theora "speed level" approach, which had a dynamic maximum depending on the encoder implementation (that, e.g., changed between releases).
Currently, nothing is hooked up to this knob.
