One concrete data point for the thread. 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.
Following on from Dr.SportsMedIN — and this may be the naive question:
How much of the between-person variation is pharmacokinetic and how much is just adherence measured badly?

Lp(a) and cardiovascular risk: a nuance that matters. Unlike most lipid markers, Lp(a) is 90%+ genetically determined and doesn't really change with weight loss or GLP-1 therapy.
My Lp(a) has remained at 72 nmol/L across all time points. If yours is elevated (>50 nmol/L), you need additional risk mitigation strategies regardless of your GLP-1 response. Don't assume your medication is covering all cardiovascular risk factors.

CRP reduction on cardiovascular risk — this is the lab result that excites me most:
Baseline hsCRP: 8.0 mg/L (high cardiovascular risk)
Month 6 hsCRP: 3.5 mg/L (moderate risk)
Month 12 hsCRP: 0.4 mg/L (low risk)
This level of inflammatory marker reduction is comparable to what you'd see with statin therapy. Combined with the weight loss, my 10-year ASCVD risk score dropped from 15% to 6%. My cardiologist is genuinely impressed.
