Magnum BMK Accuracy Question

What are all your feelings on the accuracy of a Magnum BMK set on auto efficiency.  They don't specify if you should tell it AH at 6 hour or 20 hour rate either.  We have not had very good success with Trimetric or Outback keeping calibrated in the long term.

    IMHO, it's pretty much impossible for any SOC meter to stay accurate on a LA bank over the long term, especially in situations where the bank spends many days/weeks cycling at < 100% SOC.
