In the four week HBA1C the trend of 0.175% reduction per week since January 16th sustained and the score today May 16 is 6.5% (was 7.2% on April 18, and 7.9% on March 22nd, Feb 08: 9.0% Jan 16th: 9.8% and January 11: 11.6%)
If you argue that pre-diabetes (high diabetes risk) is up to 6.4% and not 6.5%, I submit that because 6.5% is minimum 57 day average (57-150 days), for the recent 28 days maximum value logically is 6.2%.
I will put a fresh update three months from now. (I do monitor glucose level on glucometer several times a day and may continue the four weekly A1C)
I have put up my 2,200 daily diet and exercise data on this forum and will email a copy to anyone who asks for it. email@example.com
