Race statistics

Post by shawn » Thu Apr 12, 2012 6:34 pm

The races in Junior Solar Sprint are usually run as double-elimination from heats of 4-6 tracks.
A simple way to run double-elimination is explained here, in the context of pinewood derby:

Double-elimination brackets for 20 or less players, in Excel format, can be found here:

Worries about what to do with numbers of teams besides powers of two, and final heats, are addressed by the Croquet Association writer here:

This from the NREL guidebook for Junior Solar Sprint:
The Double Elimination Diagram is set up for the Colorado competition with 55 cars racing in 10 lanes. This diagram will illustrate how the competition will progress through the different heats.
RACE 1: Race cars in heats of nine to ten cars at a time. The two fastest cars from each heat move to Race 3. The remaining slower cars move to Race 2.
RACE 2: These cars all have one loss each. Race cars in heats of nine or ten cars at a time. The two fastest cars from each heat moves to Race 4. The slower cars now have two losses and are done competing.
RACE 3: These cars have no losses. Race cars in heats of eight cars at a time. The two fastest cars from each heat moves to Race 5. The slower cars move to Race 4.
RACE 4: These cars have one loss each. Race cars in heats of eight to ten. The two fastest cars from each heat move to participate in Race 5. The slower cars now have two losses each and are done competing.
RACE 5: The remaining 10 cars compete for first, second, third, fourth, and fifth place.
