Yes,  as I mentioned this is not a proof.  Neither is post-analysis, but
it would at least add some confidence.  

There is always the possibility that some nakade glitch or something
makes it return the wrong results.   

Also, the possibility that some difficult to find key move masks the
true result.  

It's also possible that a strong go program is more likely to return a
false result due to having more idiosyncrasies.   

On 5x5 and 7x7 it DID return what is believed by humans to be the
correct komi,  but that doesn't mean it will at any other board size.

I like the idea of playing thousands of games and building a tree for
later inspection.   If anything looks really wrong,  it can be further
