Out of curiosity, do you drink much water each day?
I'm kind of wondering if the people having a bad result don't drink enough water each day to clear out their systems? Yeah, that's a simplistic take... but still, curiosity. :)

Dehydration is not a confounder for an A1c test since the percentage is relative to the hemoglobin present. The primary confounder to A1c are blood disorders such as hemolytic anemias that lower the normal lifetime of RBCs or proportion of HbA. And this tends to falsely lower the A1c.
A person with an 11% A1c is also likely drinking quite a bit (whether they notice it or not) because at that point the chronically elevated glucose is elevating serum osmolality to increase urination.
