If in fact BMCC zebras are displaying IRE values when the camera is in ProRes/DNxHD recording mode, then yes, I'd like the zebra range extended down to 40% or so, too.
When the BMCC is in RAW recording mode, my understanding is that zebras display sensor clipping, not IRE values.
If instead they are IRE zebras for ProRes/DNxHD, then one of the uses I'd have for zebra values down around 50%-60% or so is for adjusting lighting for a green screen. With other cameras, setting IRE zebras in that range for exposing the green screen to get a nice even display of 50%-60% zebras usually works well for me. Once the green screen lighting is done, I then set IRE zebras to around 70% to judge exposure for skin as per usual.
Related question: Does the BMCC have to be in ProRes/DNxHD mode using "Video" (Rec. 709) (instead of "Film" [log]) gamma for zebras to display IRE values?
However, if BMCC zebras never display IRE values, but only sensor clipping, then never mind.
