If your language is complex enough (and it's my understanding that Ithkuil is[0]) that the emitter takes more time to translate thoughts into it, the transmission rate is not going to raise regardless of information density (remember rate is over time). I guess if we consider non-real time communication, but in that case (e.g. in English, which is limited by the medium's rate) the reception rate is the main factor, which is probably not too far off the transmission rate. I'd say Ithkuil is designed for information density and my guess is its actual max rate is pretty similar to the submission's 39bps. [0] IIRC not even its creator is a fluent speaker.
