Mornin' JofNile    Unfortunately by the sounds of it this new toy? hasn't settled down & the most unfortunate aspect is the lack of correspondence from the tech.  Your comment about the wide variance between cgm & meter is abnormal, said units are programmed to be cottin-pickin' close the meter  ..... that should have been done initially.  

Sure hope that Alisa sees this thread & replies, we discussed this in chat one evening & if Moi memory is still working her differential was two points.  Two points is superb for the simple fact that you must realize samples are taken from a respectable distance apart.  How many times have we heard about tests being made with different fingers with different results.
