If the AFR numbers follow some bathtub-shaped curve, would it make sense to use that curve to "normalize" the failure rates according to drive days?

I always wonder if the rates we see for each drives are really comparable, since they all have different ages, and whether that's representative of the average lifetime AFR.

That might be an interesting column to add to the reports!
