I was talking to Jonno about this lil' bit of kit yesterday. Looks interesting! I'm not sure why the boil times on the titanium burner is only 4 mins when the boil time on the Trangia burner is 11 mins. Presumably the holes in the titanium burner are better placed to work efficiently at such a close distance between burner and pot. As far as I know the Trangia burner works best with gap between it and the pot, as in the Trangia 25/27 sets. Even still, I think 11 mins sounds fairly normal for a Trangia although 300ml is probably a bit less volume than normally measured.
