@glenaxl: have updated the PowerSpectrumTest8 archive attached to first post, to dial back the borderline kernels a bit (for now, will dig deeper into those later if needed).

Good, good.  will keep those ones dialled in a bit then, allowing some possible fine tuning later.  It seems cramming that much data through we're beginning to find weak spots, so will look at moving onto FFT integration.
