MLU giving odd results

Thu Oct 10 02:14:28 UTC 2024

Peter,
    Leonid just now reminded me that I was about to work on this by creating a filter that would disregard all of the features that UD is creating except for those that align with Brown 1973.  I’ll work on this tomorrow.  Sorry about the hassle.
