If this guess is correct(I do not know it) then it suggests that maybe
increasing extended futility pruning from 300 to a bigger number may be
productive after reducing history threshold and maybe combination of reducing
history threshold even more and increasing futility pruning may be even more
productive.

Note that I have no idea if 50 is the optimal number and of course if 50 is
better than 70 it suggests also testing 40 without changing other parameters.

50 was only a guess and I did not dare to change too much so I even did not test
40 to compare with 50.
