I don't have the rules in front of me but it looks like it works like this:

The top four from each semi go to the main, that is:

From A:
Pietsch
Dankel
Huber
Leino

And from B:

Wischnewski
Krober
Spataro
Balestri

That puts 8 in. Leaves room for the 2 fastest from whichever semi, that would be:

Berntsen
Derderion

Both from the same semi as Stamler, who was 7th. You don't get a bump from 7th place no matter how fast you are because there will be two guys faster than you (5th and 6th).
