    Turns model based reverse updates on for coefficients in an
    effort to reduce the memory requirement for counters.
    
    With this patch the counters needed will be reduced by about
    75% since only 3 counts are needed instead of 12.
    
    The impact in performance is:
    derf300: -0.252%
    stdhd250: -0.046%
    
    However retraining should alleviate some of the drop in
    performance.
