here you go ! If you do this correctly you will be right on at all your far shots !
Walk back 20 yds from the target in a straight line, and using your 20-yd pin, fire at the sticker.
Don't worry about where the arrow hits.
Step back in a straight line to 30-yds and use your 20-yd pin, fire at the same sticker. Repeat at 35 yds and 40 yds.
If your arrows look like this pattern "/",
move your arrow rest 1/16th inch in any direction.
Repeat the test and fire at 20 yds, 30 yds, 35 yds and 40 yds,50 yds.
Did the pattern get more vertical?
Great, move your arrow rest 1/16th inch in the same direction.
Did the pattern get worse?
Move your arrow rest in the other direction.
Keep adjusting your arrow rest,
keep using the same 20 yd sight setting, and
eventually, you will get an arrow pattern that looks like "|".
When your arrows are straight up and down,
lock down your arrow rest position.
Now, the arrows that finally look like this "|",
may be straight up and down, but they may be several inches
away from the weighted string.
Now, we adjust windage for your sight ring.
Pick a direction. Move the sight ring 1/16th of an inch.
Repeat the test and using the 20 yd sight setting,
fire arrows at 20 yds, 30 yds, 35 yds and 40 yds.
Is the vertical pattern of arrows getting closer to the weighted string?
If yes, keep adjusting your sight windage in that direction.
Is the vertical pattern of arrows getting farther away from the weighted string?
Then, move the sight windage in the other direction.
Eventually, you will have all the arrows touching the string.
Lock down the sight windage.
Your centershot and sight windage are now perfect.
