Hi there,
Sorry for the handwaving.
I am just a bit puzzled about the methodology to estimate the probability maps, but the good thing is that the entire unexplored regions will be systematically probed (this limits the impact of the Phase IV priors), whether an airliner can exit the 20 NM radius or not, whether the maximum probability to find the wreckage is on the LKP or not. Just waiting the effective search now.
