The FRC duration depends on the number of bonded Nodes, the number of discovered Nodes and the duration needed to serve the command (FRC response time) on the Nodes side (which depends on the most time-consuming Node).
For example, the FRC duration in a full network with 239 bonded and discovered Nodes and 40 ms FRC response time (default) is:
● 34 s in STD network
● 46 s in STD+LP network
