Downsampling in HHT

I don't see how this can work in the way suggested. In any IMF Omega varies smoothly on timescales longer than the averaging time (as it must because faster variation has been removed in earlier IMFs). We do not gain a sqrt(N) advantage which would require Omega to vary randomly over an averaging time.
