There's no way to answer that with lower end operators. In stable times movement can be small to nothing, in liquid times you would barely make the minimums and get a command, subject to your own ability. That would hold true for NJS, QLink, Rex and anything else below mainline QF/VA. If QF/VA went into administration tomorrow (hypothetical) you would be stuck where you are for a long time most likely. If like now they are recruiting madly, well you will jump the ranks very quick.
