I'll probably try that at some point ... I am fairly sure I haven't seen a linear relationship in the past even off physical cores so it may be that the overheads of parallel processing in the FAH Cores is also a factor in the relationship not being a direct inverse one.

I'll get a number of other projects out of the way first then if I am not dragged back into the real world will spend some time on this ... Might use FAHBench rather than live FAH as I think that will provide a better consistency of load (by using the same WU) - and less likely to screw up real science.
