That's why I picked and chose from November 2018 AOR to make my informed prediction, which was correct. The IP2 data is mostly garbage from MyImmiTracker.
Most people there don't seem to know what IP2 really is, and IP2 seems to be non-indicative at all for people who must give biometrics (everyone after Dec 31), those who had an RPRF request (didn't pay up front) and CEC. Possibly other inlands as well, but I don't know.
IP2 seems to only be meaningful if you are non-CEC (and possibly only outland), paid your RPRF up front, and you don't have to give biometrics. At least, that's what I've deduced from the data available to me and is what I used to make my prediction.
