As we know, the yoke trim switch will always override MCAS.
That is a fairly sweeping statement that may well be true, for all I know. However, I'm still wondering about the short NU trim commands visible on the FDR print-outs from both accident aircraft. They appear so similar that I wonder if there is some feature or limitation of the manual electric trim system that has yet to be revealed. Hopefully, the accident reports may provide some explanation.
