    In X4M200 Respiration Normalized Movement List Message, what is the scale of the values in the lists: NormalizedMovementFastItems and NormalizedMovementSlowItems. And more importantly what is their upper range? I'm getting float values well over 5000.0. I need the expected range of these values.

    This doesn't correspond with the explanation of the single movement values and also the range in xethru explorer from -20 to 30.

    In normalized movement list array, every value has a theoretical range from 0 to ∞, but most of them are between 0.01 to 1000 from observation. On XeThru Explorer, we use dB value, the formula is show_value = 10lg(float_value), so you see y-axis range is -20 to 30.

    OK, thanks. Just to confirm, each element in the list is movement in the bin at that index?

    Yes, your understanding is correct.
