It's got to be something in the hardware, that's all I can come up with because the reality is such a mystery to most people. I’ve seen, and forgive me I can’t seem to find the link again, head to head compressions of the exact same NF2 motherboards (e.g. multiple boards of the same type and from the same maker) where the numbers varied wildly. This, for a long of a better term, phenomenon is something that seems to be very wide spread on all NF2 boards except for the DFI boards, which is one of there strongest features in my book.
