I’m aware of the limitation of the buffer system. But during the Signals scenario, the same engineer developed some transsporter tech including retransmission without materialisation. and won the cochrane medal of transmeters. Yes they can use n+1 transmetters buffers to store n people that are cycling. And yes if they make a roll they can duplicate the away team signal. they use it as backup in case of problem or for comparaison. Some technical issues prevent them for overusing it (they don’t want to have multiple copies of themselves if I spent some threat on a 20 roll)
