BRACKET RACE 2013
For the first time in proxy racing Black Top Raceways and NTRA will host a bracket race. Bracket
racing is a method that will allow cars of various levels of performance to compete against one another.
The differences in performance is equalized by staggering the tree to give the car of lesser performance
a head start. The amount of head start is determined by a dial-in time submitted by each car prior to
the race. Cars set their initial dial-in based on ET's run during qualifying runs. After that the cars dial-
in is set based on the last ET obtained. Dial-ins during 1:1 events are usually set by the driver or a
member of the driver's crew. In proxy racing the entrants are not on hand to provide round by round
dial-ins. This would mean that entrants would only build the car and turn over the task of determining
dial-ins to the proxy drivers. This way of proxy bracket racing excludes the builder from being a part
of determining dial-ins for his car. In an effort to keep the builder a part of the bracket race process,
a dial-in tool was developed to allow the builder to predetermine how dial-ins will be calculated during
the race. The builder is now involved in the dial-in process and the drivers now only focus on cutting a
good light.
HOW THE DIAL-IN TOOL (DIT) WORKS
The dial-in tool is in no way perfect and will never substitute calls made by humans. But it is for now
the best method available that will make it possible for the builder to predetermine dial-ins. The DIT
allows the builder to submit a percentage that is applied to the qualifying average or ET of a previous
race. For example: a car has a qualifying average of 1.000; the builder elects to use a percentage of
5%; when the percentage is allied the the qualifying average a dial-in of .950 is calculated for the first
race. By applying this percentage there is less a chance of the car to breakout (exceed its dial-in
time). Another user willing to take more risk may use a percentage of 2%. Using 1.000 as a qualifying
average, this car will have a dial-in of .980 for its first race. This car has a tighter dial-in but is more at
risk of breakout. Subsequent races use the ET of the previous race to which a percentage is applied.
As the race progresses it is supposed that dial-ins should get tighter to increase a cars chances of
getting the win. However, as your chances better so does the risk of breakout. To simulate tightening
the dial-in the builder can select a 'regression factor' that can be applied to the initial percentage. The
way this works is a builder that has selected 5% can choose a 'regression factor' of let's say 1. The
builder is now electing to use 5% as its intial percentage and the DIT will decrease that percentage
by 1 each subsequent race. So a builder that starts at 5% with a 'regression factor' of 1 and also has
a qualifying average of 1.000 will have their calculations progress like this:
QT 1.000 (assumes all subsequent ETs to be 1.000)
1st race dial-in .950
2nd race dial-in .960
3rd race dial-in .970
4th race dial-in .980
5th race dial-in .990
6th race dial-in 1.000
. . . and so on until car wins or loses two races.
In this case the regression has zeroed out by the 6th race. From that point on, the DIT will use the ET
of the previous race as the dial-in. The builder continues using the best possible dial-in, but is most
vulnerable to breakout. Not every builder is going to want run their car at such high risk. So another
feature of the DIT is that the builder can put in place a 'regression stop'. What this will do is place a
limit on how low a percentage will regress to. Using the above example and adding a regression stop
of 2%, the percentage will decrease by 1 every round until it gets to 2%. At this point throughout the
remainder of the race 2% will be applied to previous race ETs.
BRACKET RACE PROCEDURE
The Car.
For this race only inline chassis are allowed. Must have a Street or Drag body. Chassis may be set
up as desired by builder. When submitting your car, in addition to labeling car with entry number,
and any warm-up instructions. You will also want to include a DIT set-up. The DIT set-up requires
three numbers, initial percentage, regression factor, and regression stop. The DIT set-up that is
submitted can be changed after qualifying runs are made. After qualifying times are provided,
builders will have approximately 24 hours to submit new DIT set-up numbers.
The Race.
Two runs minimum (racemaster's digression to run more) will be made in each lane. The lane a car
does best in will be recorded as its favored lane. The average from that lane will be the time that the
initial percentage is applied to in determining the first race dial-in.
Qualifying times will be posted as soon as available. Now knowing your times you may adjust your
DIT set-up numbers. A submission deadline will be posted along with the qualifying times. New DIT
set-up numbers must be submitted prior to the deadline. Cars submitted without DIT set-up numbers
and none are provided prior to the deadline will be given a 5% to be used throughout the race.
Once dial-ins are established for the first round the DIT then makes any remaining dial-ins based on
the DIT set-up numbers submitted.
This will be a double elimination race. A car must lose twice before being eliminated from the race.
Hopefully, the above explanation somewhat clear. Please post any questions you may have concerning
the DIT or race procedures. Otherwise, build those cars, the race is only weeks away. Keep in mind
consistency and not speed is what is key here. See ya at the line.
