Thanks for the interesting info!

The point I am trying to make is that if this is a typical phenomenon - i.e. if
an N-man TB is not just hit a lot from 3+N but maybe from 2*N or higher -, we
may be "a little" closer to perfect play because we will certainly not need the
infamous "32-man TB".

If for example a 15-man TB is already hit a lot from positions with 22-28
pieces, we are many orders of magnitude better off.

Now 15-man may still be out of reach for a looong time, but maybe 10-man is
possible within the next 50 years; that would make middlegames really tough for
humans if the machine starts hitting the TB's in situations with 18-25 pieces...
