Joerg-
Why can't you have more elements than nodes? You definitely can. See attached mesh with 24 elements and 17 nodes.
Also, I created a simple cube and meshed with an extra fine mesh resolution with the free tetrahedral mesher.
Results:
~400k linear elems
~69k DoF (nodes)
That is a ratio of 0.175 -- very close to the value given by the Knowledge Base post you referenced:
(#of DoF) = 0.2 * (#of Elems)
