This is from the IBS Rule Book so take a look at Short and Long Range in the rule book.
Again I am not here to point fingers at any places or anyone like you are you continue to ask for, those questions have nothing to do with this post.
Draw your chip from a can and good luck at your next match.
The IBS LR rules are written differently:
Relay and Bench Assignments. The over-arching tenet is relay and bench assignment must
be done fairly so as to not discriminately advantage or disadvantage any shooter, regardless of
their experience or seniority in the sport. Designation of shooting positions and relays shall be
determined by individual Clubs, per below rules.
Clubs conducting Registered Tournaments do not routinely have the privilege of permitting
competitors to select their relay or bench assignment. Three exceptions are allowed. First, an
exception may be allowed to accommodate legitimate requirements a shooter might have such as
a scheduled doctor’s appointment that day, as an example. Second, physical handicap may be
accommodated. Third, Clubs have the option of assigning all non-IBS shooters to the same
relay(s). Exceptions are considered and can be granted by the Host Club Match Director or
Statistician.
Computer-Based Program. One method uses a computer-based program to randomly
assign shooters to relays and benches. Typically, this random generator is used to determine
relay and bench assignment for each individual Match by class.
Drawing. A second method is conducting a drawing for benches. An example is each
shooter pulls from a container colored and numbered chips that indicate relay and bench
assignment. Another example is each shooter selecting one face-down playing card. One of the
Referees or the Statistician shall be present to see the drawing is fairly conducted and to
represent registered shooters not present when called upon to draw. Clubs have the option of
having but one drawing and requiring each competitor to shoot from the same bench for all
matches in a class at all distances or they may allow two drawings - one for matches at the first
distance and one for the matches at the second distance. Clubs may also draw for each Match,
each class.
Shooters in the 600 Yard discipline commonly share wind flags. With the permission of
the Range Officer or Statistician, a competitor may identify up to three other competitors to share
bench assignment at the time of bench drawing. He/she must declare the other individuals prior
to any of the individuals drawing for benches. The Host Club will accommodate the request up
to available benches on currently open relays. This option is not open to the 1000 Yard
discipline.
....etc.
