I keep track of my bs readings and my insulin use on a spiral notebook. I then enter the data into my diabetes software "Diabetes Pilot". This software will run about 15 different types of reports, each shows some different ways to look at your bs readings. My readings from my meter show a different average (higher) than my last A1C which was 4.4 which is too low. I don't know what to make of this. If anyone has any ideas, please share them with me since I am truly confused. I think I have above average intelligence but I am stumped. I have yet to run across any type of meter software that is compatible with Windows 7 operating system and will work properly. Even the new Bayer USB meter is not compatible with Windows 7 and I have read a number of reviews and most indicate problems.
