Adding the numbers, since they settle part of this. Worth knowing that the injection site changes very little. Abdomen, thigh and upper arm are bioequivalent for semaglutide, so a site change is not a plausible explanation for a bad week.
A narrower follow-up, since the general answer is now clear:
What the dose-response curve actually looks like above 1.7mg, because the trial means hide how few people account for the extra loss?
HPLC_Greg said:Worth knowing that the injection site changes very little.
Coming at HPLC_Greg’s question from a different direction. 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".

Six weeks on from posting: I stopped reading the weekly number and started reading a four-week average, and the "stall" I opened this thread about was a 1.8kg loss I could not see.

No disagreement with SarahChen_PharmD. One condition attached. 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.
