Sometimes your recent glucose values in LibreLink (and therefore in Veri) can change. This is due to LibreLink predicting your glucose based on whether it detects your glucose to be rising or falling. In a nutshell, LibreLink will show a predicted value at the time of reading, which can later adjust if the prediction is incorrect. Below, we give an example of a failed prediction and adjusted score. Though the example is in mmol/L, the same logic applies to mg/dL.
PICTURE 1: 23:54 - glucose is rising, Librelink (and thus also Veri) shows 7.2mmol, but Librelink always tries to “predict” glucose - so when your glucose is going up it will show a higher number, when going down it will show a lower number.
PICTURES 2&3: 00:06 - LibreLink & Veri - the peak is now just 7, and the value at 23:54/55 is just 6.7 now (down from 7.2 in the previous measurement)
This happens because the original LibreLink “estimate of rise” was wrong and the past value got corrected.
PICTURES 4&5: 00:29 - the peak was just 6.8 and now we’re back to 6.7
The past values changed twice both in Veri and Librelink, after the wrong prediction was corrected again.
