Multi-stream slice offsets

I see. yeah the number of neighbours change the whole time.
I will have to dig it.

what about dynamically exclude streams from a network by only use 2 of 4 than 3 of the 4 streams ?

I knew about fl.unpack but i was not sure about how to get the n distance values into the multistream. As i just learned Fl.*~ wont eat a list (with changing size) straight away… i would like to prevent using unpack for flexibility reasons.
