Good evening
@Sadsac@21 and welcome to the forum.
Well done for changing your lifestyle and losing some weight.
You cannot extrapolate from finger prick blood glucose tests or CGM readings to HbA1c results, because they measure different things.
The fingerprick test measures blood glucose at that instant. You only have data for the times you test, so no information about what happens while you're asleep, for instance.
The HbA1c test counts the number of glycated red blood cells; that''s the cells that have had a glucose molecule attached to them. Because red blood cells live about three months, glucose levels from three months ago still affect an A1c reading today.
Although HbA1c results are skewed towards the most recent weeks, you cannot expect BG readings to forecast your A1c result. That said, it sounds as though you're well on your way to managing your diabetes.
