Here is the thing you are probably counting wrong if you want to match the
numbers some give here...  when depth=0, you call quiesce(), and _that_ node
is _not_ a q-search node, because there is _no_ choice involved in whether
to reach that node or not.  Nodes _below_ that are 'optional' depending on
your capture rules...  I don't count like that as it is more difficult, but
if you wanted to have a Search(), Leaf() and Quiesce(), then you could
count things and discover that it is possible to really get pretty low on
nodes searched by Quiesce() above...
