How does this format work?

Duelling Over Grand is a double elimination knockout format. Two crews race head to head with the winner advancing to the next round via the "undefeated" tree".  Once a crew loses a race, they go into the "second chance tree" and progress through until they either lose a second race (and are knocked out of the tournament) or win all their races and advance to the Sunday Championship Final. 

The winner of the "undefeated tree" and the winner of the "second chance tree" meet in the  Championship Final, held on Sunday.

The "undefeated tree" races (labelled "A") are held on Saturday; the "second chance tree" races (labelled "B") are held on Sunday. 

Each crew is guaranteed 2 races and may race as many as 6 times (depending on the number of entries).

BYES: Because of the nature of the dual format tree, some crews may get a "bye" in an early round. Crews that have a bye do not row down the course for that round of racing. 

NO SHOWS: if your competitor does not show up at the start line, you are awarded a win but you are required to row down the course and across the finish line at a pace that does not impede the following racers.

SCRATCHES: if your competitor scratches before you launch, you do not need to launch.

For the DOG regatta 2017 we switched to Regatta Master (RM) to better manage the regatta and races. This allows us to address the following deficiencies of the old system:
1) In the old system it was common that a crew had to race the same opponent in the 2nd chance tree that they lost to in the undefeated tree. With the new system, you will be less likely to race the same people.
2) The old system assigned the initial spots based on a "sort by club name" therefore same clubs regularly raced each other in different events. The new system uses a computer-based random algorithm to allocate crews to the initial spots in the progression tree. The new system is capable of seeding for championship events.
3) The old system did not support new boat classes.
4) The old system did not have scheduling flexibility. The new system provides this flexibility. More rest is scheduled in between progression levels of events with the greatest number of entries and before the championship finals.
