By the way, I didn't "pile praise on DB".  I said (a) they are 100x faster.
That is not praise, that is fact.  I said (b) they tuned in a different way,
using GM opponents rather than autoplaying against other programs in an effort
to top the SSDF list.  Neither of those are "praise" but are "fact"...
