You are comparing search times with each other. That is
correct way to do it. He isn't comparing search times with

Also he claims that his near to fullwidth search is just needing
only 50% more nodes than with only nullmove. God knows how he
managed that. For me fullwidth versus a search with nullmove
is plies difference. Not 50% in nodes.

So his own results, seen from time viewpoint also show clearly
that nullmove is superior to his verification search.

Bad new name for something already existing.
