More info on my sensor experience. It seems to me that there may even be variability not just between devices and methods of testing BGL, but also between the sensors themselves. My BG has ranged widely in the last 48 hours, and I am on my last available sensor. Readings have been pretty much accurate no matter which method I am using to test, so for the rest of the month I'll probably just stick to the sensor unless there are anomalies in the reads (eg super high or super low). No wonder the government wont subsidise it. Abbott has to do more about safety... because such inaccuracies are not safe, especially for T1s.
