Is it getting better or worse?

Holding steady.

Your daily average was 108 mg/dL over the first half of the days you wore it and 107 over the second — a difference of 1, smaller than the 5 your average moves from one day to the next anyway.

61 days of FreeStyle Libre 3 readings with at least 18 hours of wear, Jan 2, 2024 – Oct 31, 2024. Each dot is one day's average. The dashed lines are the two halves being compared, and the band underneath shows which sensor each day came from — S1 first, then S2, in the order you wore them.

What was checked before saying that

Did you wear it as much in both halves?

You wore it 24 hours a day in the first half and 24 in the second, so neither half is thinner than the other. 8 part-days left out for having under 18 hours.

Did new sensors line up with the change?

You wore 6 sensors, and one of them was on for a good stretch either side of where the halves split — so this is not simply one sensor against another. Their averages ran 93–113 mg/dL. Your last sensor also sits 17 mg/dL below the others, which is what the run of dots at the right of the chart is — a new sensor, not necessarily a new you.

Is it bigger than the day-to-day wobble?

Shuffling your days between the two halves at random produces a gap this big about 60% of the time, which is often enough that this one proves nothing. Dropping each sensor's first day leaves a gap of 1 mg/dL across 54 days.
