Here are a couple of graphs from my CGMS. I've found it to be quite accurate in terms of being on the money (or darn close) to my BG meter (using the One Touch UltraSmart in conjunction with the CGMS). Though I tested my BGs with my meter more than what is shown, almost all the meter readings were either right on the money, or extremely close (i.e. within 10 points of the Sensor Glucose) to the CGMS. I took a break from the CGMS & am not happy being off it...that said, wanted to save that last sensor till I was ready to buy more.
Here are a couple of graphs to provide examples of how I've been doing when on it:

I'm very pleased with the output & results I'm able to achieve by using the CGMS. I'd strongly recommend it to anyone who has an opportunity to try it.
