A quick post, just because I found this example particularly clear and interesting.
Tennis starts at 16:00 – we see a huge drop (50 mg/dl in one reading) at 16:25. We stop and double BG test at 16:30: 95 mg/dl. The sensor goes to LOW and starts beeping. A new BG still tests around 90 mg/dl while the sensor is now in LOW. At 18:30, tennis is over and, since the sensor is stable, we recalibrate. We are still around 100 mg/dl. The algorithm picks up the new calibration factor almost at once. That would have been very different with the G4 non AP: a new significantly different value would have had a variable impact depending on the previous values the calibration table held (or even the number of calibrations in the table if the sensor had been recent)
Since we’ve not seen an evening meal rise (frequently absent after intense exercise), I suspect a delayed hypo is in the book, which is why I double check and re-enter a calibration just in case. The guesstimate was spot on: we go down the slide. The sensor then accurately tracks the real delayed hypoglycemic even, which we correct (duh!).
