When Official
Mileage
Accumulates
Throughout
a Rally…
When mileage accumulates throughout a rally without resetting to 0.00 at checkpoints, there
are, again, two possibilities: mileaged outmarkers or no mileaged outmarkers.
If mileaged outmarkers are provided and your out-time is from that point, use the steps
outlined in “
When Official Mileage Resets to 0.00 at Leg Outmarkers…
” except that in
step 4, actuate
T RU N CA T E
only. Then adjust the
O D O M E T E R
(using the
O d o m e t e r
position on the rotary switch) to the official outmarker mileage. (If you do actually reset the
odometer to 0.00, that’s OK, it just takes longer to set the official mileage.)
When outmarkers are not present and your out-time is given from the in-line of a checkpoint,
use the steps outlined in “
…and Mileaged Outmarkers Are Not Provided
” except that in
step 3 adjust the
ODOMETER
to the official mileage for the in-line (on the checkpoint
critique slip), rather than 0.00 miles. If desired, in step 1, you could actuate
SPLIT
and
CAST
simultaneously if you don’t want to truncate the
O D O M E T E R
and
CA L CU L A T E D
T I M E
. This will still allow a Retro-CAST™ back to the in-line should the critique slip
change the starting CAST for the new leg.
Do It Yourself
Checkpoints
When designing a rally course, rallymasters often use “Do It Yourself Checkpoints”
(DIYCs). DIYCs allow the rallymaster to score a leg of the rally without having checkpoint
workers monitor the passage of each rally car. Instead, you record your own “official time of
arrival” at an indicated reference on the course. Obviously, you can record a calculated time,
rather than your actual time of arrival.
As for all legs of a rally, the 798A calculates the DIYC travel time using the distance you
drive and the CASTs you enter. Since the calculated time is not dependent on actual driving
time or speed, you can usually proceed along the course at your own pace. Of course, you
must arrive at the end of the DIYC early enough to begin the next leg of the rally on time.
The general procedure for executing a DIYC is as follows:
1. Follow the course, executing all the CAST changes at the correct locations.
2. At the end of the DIYC, record the value in the
CA L CU L A T E D T I M E
display.
This is your “calculated in-time” for the DIYC. The difference between this value
and your out-time from the previous leg is your “official leg time” for the DIYC.
Record these values as directed by the rallymaster.
3. Actuate the
TRUNCATE
switch.
4. Enter the next CAST into the
SPEED
display. If the CAST doesn’t change at the
start of the new leg, skip this step.
5. Add to your calculated in-time the amount of time (if any) you are to pause at the
DIYC before starting the next leg. Use the
Calc Time
function to add this pause.
The new value in the
CA L CU L A T E D T I M E
display is your “calculated out-time”
for the next leg. Record this value, too.
6. Pull beyond the end of the DIYC a safe distance. As the
ERROR
display on the
driver’s module nears 0.00, proceed into the next leg of the rally.
Correctly executing a DIYC is probably one of the easiest ways to score a zero on a leg of a
rally. Unfortunately, rallyists are so often concerned about DIYC procedures that they make
course errors. Keep in mind that the purpose of a DIYC is often just to reduce the number of
rally workers. The determining factor in DIYC scores is usually proper course following.
