I do not accept that the fasting window is a minor inconvenience. Adherence data on daily orals with timing requirements is consistently worse than weekly injections, and a drug you take imperfectly is a lower dose than the one on the box.
Adding the numbers, since they settle part of this. For anyone assembling their own picture: Tmax is one to three days, terminal half-life about 165 to 170 hours, steady state at four to five weeks, and subcutaneous bioavailability near 89%. Those four numbers explain most of the questions people ask about timing.
Ask again with the specifics and you will get a better answer than this one.

There is a second half to this that has not been said yet. The dose-response is real but shallow at the top. Across STEP 1 and STEP 4 the gap between 1.7mg and 2.4mg is a couple of percentage points of body weight on average, and the average is carrying a wide spread — plenty of people at 1.7mg sit above the 2.4mg mean. If a dose is working and tolerable, "working" is the relevant variable, not "maximal".

How much of the oral variability is the SNAC absorption window and how much is dose, because the two get conflated constantly?

I moved the tablet to the moment I wake up rather than trying to fit it around breakfast, and the difference in the following weeks was obvious. It was a timing problem, not a dose problem.
