Fair questions.  All of the other evidence I have seen has been anecdotal.
There is the case where Bob said that DT returned +2 or something against Cray
Blitz.  I tried that one for a long time and never got anywhere near +2.  I
might be able to dig up the FEN for that.

But I don't know of published cases other than these Nolot tests where we have
difficult tactical shots, and times taken to find solutions.

I don't say that they don't exist, but if they do I haven't seen them dissected
out and presented with any degree of rigor.
