I have done this many times myself so this isn’t surprising to me.

I always go by Contour Next and Accu-Chek. Their averages are very close with my A1c and Accu-Chek was spot on when I compared its reading with a lab glucose test using the same arterial blood sample a little while ago, which I always recommend others with diabetes do.
Haven’t tested the Contour Next One (my current meter) but have compared it with Accu-Chek many times and they’re very close.
What do you all use and what are your thoughts?
