Yeah, I ran Diehard on it .. and that is why I wanted to find some
references on removing bias.

This is a neat idea. I smiled when I read this in RFC1750

"Two things fill the mind with ever new and increasing admiration and awe
the more often and steadily we reflect upon them: the starry heavens
above and the moral law within me. I do not seek or conjecture either of
them as if they were veiled obscurities or extravagances beyond the horizon
of my vision; I see them before me and connect them immediately with the
consciousness of my existence." - Immanuel Kant "Critique of
Practical Reason"
