Believe that there is too much "noise on the data" to trust fingerprick results anyway.
My benchmarks instead are my A1c percentages, blood pressure and weight, which I have monitored at the health centre.
Plus, I also think the assessment of the whole clinical picture: A1c, lipids, kidney function, etc does take some interpretation, which I am happy for my physician to do.
In any case, the cost of testing strips is prohibitively expensive.
