It is indeed flawed green. If you look at Denny's predictions. He has named the folowing:
Stormers
Bulls
Highlanders
Chiefs
Crusaders
Reds
The sad reality is that, if he is 100% spot-on, and they end in that order according to their log points, that is not the order that they would end up on the log. The order would be:
1. Stormers - SA Conf winners
2. Highlanders - NZ Conf winners
3. Reds - Oz Conf winners
4. Bulls - next highest placed on the log after the three conf winners
5. Chiefs - next highest
6. Crusaders - next highest.
This would mean that even if the Bulls end up one point behind the Stormers and 20 points ahead of the Highlanders and 25 points ahead of the Reds, they will still be placed in fourth spot, and the Highlanders will have a free ticket to a home semi-final.
