Nope, it was a copy/paste error on my side. Actually the 19291 nodes are 11%
of all nodes, not 1%.

Aha! Thats was my fault then. I divided it with the number of positions
a search was applied to. [ Of course it would be also a good idea to increase
this percentage, but that's a different subject then. ]
Thanks for pointing out my mistake!
