I think it matters "a factor of 2".

1) it helps you to prune
2) you get better evaluation in the upper plies when you can return a score
based on a deeper search.

number one will show itself directly because you iterate deeper, the second one
you don't "see", but it does improve depth along some branches in the same way.
