Assuming you can already shoot a very consistent group.................
Start at 5 yards and pick an aiming point that will make you hit high up on
the center of the target butt. Shoot one arrow. Then move back 5 yards and
shoot an arrow using the same aiming point as the first. Keep moving back
and shooting with same aiming point until you get to the bottom of the
target butt. Now look at your pattern. If the pattern produces a straight
line (down or at a slight angle) you arrow spine is fine. If the line bows
out in an arc, then the spine is not correct. Assuming a right handed
archer, if the curve bows out to the right, your arrows are under spined, to
the left over spined. If the pattern goes straight down your arrow rest is
in the correct position. If it goes left then you rest needs to go right and
a right slope to the pattern mean the rest has to go left (for right or left
handed archers). Now SCA arrow rest aren't adjustable. However if you rest
is a separate part try to get a different one. If you are shooting off a
self and the rest needs to move away from the bow, then you can add
material. If it needs to go into the bow, you are out of luck. If you shoot
a horsebow or ELB try changing how you cant the bow.
One more test, strip the feathers off an arrow. Go to 5 yards and shoot it
into the several times, making sure you are aiming dead level. If the nock
is almost always pointing up from dead level, you need to lower you nocking
point. If nock points down, raise the nocking point.
