Suggestions, new monitor readings higher, messing up my calculations.

I'm not disputing the accuracy. The trend is the very issue I'm having, it's going from a steady reduction to a sudden increase, across all the metrics.

I have had this with some meters in the past, and also, notably, when they changed home glucose monitors from being whole blood calibrated to plasma calibrated which meant that the glucose targets we were to aiming for were narrowed and reduced.

It is frustrating, and I understand it from a recordkeeping point of view, like when I used to get occasional Libre sensors which falsely read hypo levels for days, throwing my records and reports out of whack.

If you are happy with the Contour blue, would it be possible to split your records and start building up your data set from the point of change so that direction of travel etc is only measured from when you had the new meter?
