Heinz (and Albert),

thanks very much for testing this. I will put this data together when we are
deciding about Rybka 1.2.

I can add that VP can be at most 6 or 7 rating points better than SP, while
there isn't really any limit going in the other direction. SP performs an
additional "tactical check" which causes a slowdown of around 10-12%.
