I know that you did not try to seperate between them but my point is that if you
want to do the same as humans in the search then changing the search is not

Humans may search position for some seconds and decide that this position is not
good and later search the same position but decide that it is good for them not
because they search deeper but because they learned to change their evaluation
based on searching other lines that leaded to a similiar position.
