Yes, that would be right IF both players had an equal chance of winning the game. At least in 5-in-line this S-B system only makes an already very unfair system even worse.
As I mentioned earlier, with optimal play the one making the first move should always win in 5-in-line. Now if there are 2 very good players in the section, the one getting to play white against the other already has a really HUGE advantage. If we add S-B points we have a situation in which the other player cannot even compensate his bad luck of having to play black by winning all the other games even if the other good player lost one game against a lesser player.
And of course this 15x15 board (which is the best size, don`t get me wrong about that) compared to IYT`s 13x13 makes the white`s advantage even bigger.
So in this tournament system even the best player needs luck to win a section. For example, I`m not THE best 5-in-line player in the world, but I`d really like my chances against a world champion in a BrainKing 5-in-line tournament. That is, if I got lucky and got white in my game against him.
