RBE node in narrowband

I wonder how the "start value" field is used by the RBE node in narrowband. I thought it would be used as the last input value but could not make it work that way.

Also I am puzzled why this field exists when the selection is "block if value change is greater than" but does not when the selection is "block if value change is greater or equal to".

I think you are right in that the Start Value should be present in all cases where compared to last in/out value is selected. I suggest raising an issue for that.
Where it is available it seems to work for me. Can you provide a simple flow showing it not working?
