THREE STEPS TO RUNNING A MONTE CARLO
STEP 1
At the start, you have been given the Official mileage to 'Minimum
distance' (MD), and the speed to use. It is therefor possible to calculate the
time at which you should arrive. This is done by taking Official mileage,
multiplying it times 60, and dividing that number by the assigned speed. The
result is a number in minutes and hundredths of a minute. To convert to
seconds, multiply the hundredths portion by 0.6.
OFFICIAL MILEAGE X 60 (for Leg 1) 9.34 X 60 = 23.35 (23 min., 21 sec.)
ASSIGNED SPEED (CAST) 24
This time added to your Out time will give you the time at which you should
leave MD. If you are just out to enjoy the drive, at that time leave MD at the
new assigned speed. This should give you an error of less than one minute.
STEP 2
To improve on your score, do the calculations in step one plus the
following. Using the provided tables, select the 'Time per tenth of a mile' for
the assigned speed from MD. At each interval, the navigator informs the driver
that another tenth of a mile should have passed. The driver simultaneously
checks the odometer, and adjusts his/her speed to get the required tenth at the
required time. This should give you an error of about ten points per leg.
For leg 1, which has a Cast of 30 from MD, the interval is 20/100 minute,
or 12 seconds per tenth of a mile. Twelve seconds after the time to leave MD,
you should be a tenth of a mile down the road. 24 seconds after the time to
leave MD, you should be 0.2 miles down the road, and so forth.
STEP 3
To further improve your score, you will have to do more calculations.
Since your odometer and the Rallyemaster's probably do not exactly agree, you
will have to adjust mileages and times to account for the difference. To
calculate the odometer correction factor, divide the Official mileage by yours
at some convenient point, (such as the end of the Odometer check). Official
mileages (such as the mileage at MD) divided by the correction factor will give
you reading on your odometer. The correction factor times the interval used in
Step 2 will give you an interval correct for your odometer. For example, if a
rallyeists mileage at the Odometer check (8.58) read 8.75, the correction factor
would be 0.98. MD would occur on the rallyeists odometer at 9.53 instead of
9.34. The interval time used after MD is then 19.60 hundredths, instead of
20.0, or 11.76 seconds instead of 12.0.
This will be explained further at the rallye school.
Good luck and enjoy the rallye
