Hello again:
Paul Byrne has published Perft(13) number (hoping no bugs in his code):
http://talkchess.com/forum/viewtopic.php?topic_view=threads&p=432579&t=41032
Perft(13) = 1,981,066,775,000,396,239
Finally, my interval was wrong in only 0.02% (upper bound) or 0.04% (lower bound); the central value of my interval was wrong by 0.03%. My interval had a width of 0.01% (respect the central value), so
Perft(13) is out of my interval (as expected), but by a narrow margin.
Regards from Spain.
