Just to let you know: I did a comparison of the playings strength vs. playouts.
This time I used 4 times the oakfoam playouts for pachi (eg. 1000 for oakfoam 4000 for pachi) The graph shows how bad we become (in comparison) with more playouts:(. >From the games the first impression is, that the joseki becomes worse with more playouts e.g. http://www.physik.de/playouts2.pdf The plot is 1050 games fitted with a 5th order polynome. The borders of the plot are not statistical significant!
