Can you explain a logical reason that a change in the hash tables gives opposite
results against humans.

The only logical change that I can understand against humans and not against
computers is to play faster.

Does 64 Mbytes hash play faster?

If it does you can solve the problem by using faster time control and tell the
program against humans 4 2 time control when the real time control is 5 3.

If it does not play faster then your theory seems illogical.
