I am not sure precisely what you try to express here, but to me it seems
completely obvious why null move pruning reduce the % of fail highs on the
first move.  In nodes where the null move search fails high, the side to
move usually has a very good position, and the first move searched (if
no null move pruning were done) would almost certainly have failed high,
even if it is not the best move.
