The diagonal created by the boldface numbers
indicates the boundary between acceptable and
unacceptable parameters. Numbers above the
diagonal are acceptable margins of error; numbers
below are unacceptable.
A good rule of thumb is not to exceed 10 feet off the
road for every 100 feet shooting down range to the
targets. If you want to target vehicles 500 feet down
the road, for example, set up no more than 50 feet
off the road.
Remember that the cosine effect is always in the
motorist's favor.
