Will you consider... Nice to meet you too Betty. Because you bring up the 10 points off I wonder if... because you have 2 receivers and because they say you may have 10-15 min lag from interstitial readings.... did you ever did a comparative study in which one receiver you calibrate normally and one receiver you calibrate with 10 points less than the meter number? I'm thinking 10 points will take off the lag(maybe) and maybe this way the receiver will always alarm a low before is a real low(Mr Dex show 79 and the finger stick is 89). I'm thinking of this scenario because we had instances when Mr.Dex said 85 or 82(low alarm is 90) and finger stick was 74 or 68. I think if you can/will do this, will be very interesting to see how the 2 receivers compare.
