Putting this up for argument rather than for agreement. I have read it twice and I am still not certain what it supports.
Steady state is the thing most people miss. The terminal half-life is about a week, so every dose step takes four to five weeks to fully express itself. Judging a step at day ten is judging the ascent, not the plateau, and it is the single commonest reason people escalate before they needed to.
Where I think it is weakest: the comparator does most of the work in how this gets reported, and it is not the comparator most people think they are citing.
The bit I cannot resolve on my own is how much of the between-person variation is pharmacokinetic and how much is just adherence measured badly. I have searched first, so if this is covered somewhere point me at it and I will read it.

Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.
