Well, I was wrong! I may put the 1-12 back to a 1-15 for breakfast because he went to 69, and the alarm went off, I didn't test just gave him the tabs and he went right back up. I will test when he is going to eat again, it is looking just fine right now. Funny side note they both alarmed at the same time for the 80 alarm, i went down and they showed he was 75 on both dexi's at the same time then one showed he went to 69 the other to 72 and then the carbs kicked in and he went to 145. I do think it is interesting when both show the same # if I haven't calibrated them to be the same. I will likely calibrate them both at the next test. I have no clue when that will be because he and his brother are playing starwars and with the light sabers in the family room down stairs... they really love those silly light sabers.... they also have the x box going so it may be a while before hunger comes a callin'
