1) i didn't test anything myself, i only used logfiles bob made publicly
available

2) bob's logs are AFAIK all for normal null-move search on, no comparison
between null-move and non-null-move search.

so my tests don't even exist and they don't disprove anything :-)

in fact, the point of my excercise was to show how things should be done, by
quoting errors instead of flaming each other...
