Show me the data that shows DB can beat today's programs on
today's fastest hardware 90% of the time at 40/2.  I do not want
opinion here, you say 90% of the time, that is a bold statement
and I want to see hard data support.

DJ 6 on 8x-700 => TPR=2702
97 DB          => TPR=2862

A difference of 160 points in favor of 97 DB.  That does not imply
that 97 DB can beat DJ6 90% of the time.  That gives a 72% probability,
keeping in mind that 50% means equality, 72-50=22% or about what
Ed said!  A TPR of +366 points is required for a 90% expectation.
You must filp a very weighted coin.  :)
