7. on nodes 1-4 I am doing (adjusted for the nodes IP):

At a guess you're probably not waiting between joins to ensure that each new node has finished joining before starting another node join.

BDR really needs to be enhanced to either support parallel join of multiple nodes or identify and reject it.
