Well I guess this deserves a separate single post.?

Correct. The moves were and are within the evals.
But as can be seen it is posted as a question since I know something
is wrong. It is not possible to play Nunn at given time X then replay
the same way and get a difference of 15-5 - 9-11. So something must
be wrong but at that point I wasn't sure what and I assumed I would
receive suggestions as to what the problem could be.

Correct the moves were and are within the evals.
I rebooted and played over getting the same score as the first
set 15-5.

The rerun proofed the score of the original score.

Sadly I do not post every movement I make or when I go to the stores.

The moves in the 11-9 games were within F6 evals. But the depths of
those moves were not as deep as they should have been given the same
time for the move in analysis. This as stated elsewhere was discovered
by Uri as being the case for Crafty at 25/0. It was at that point that
this was discovered and since I have made no posts on the subject since
that time so there is no post where it is stated.

If you believe Crafty can win 5/0 Nunn 1 against F6 then have someone
play the match and you will see that infact F6 wins easily.

Thanks.
