I,m a little confused it is impossible for a bow to be set up so all the arrows miss by the same amount to one side over different distances.

I am not that great of an artist.
My first version of the picture,
I just used one mark(small triangle) per distance,
so I showed just one arrow mark for the short distance,
one arrow mark for the medium distance
and one arrow mark for the long distance shot.
Then, folks looked at my drawings "literally"
and assumed that walk back tuning was only for expert shooters,
who could get the arrow to hit the hanging string
from 20 yds, 40 yds and 60 yds.
I explained that walk back tuning is for beginner shooters
and intermediate shooters and expert shooters.
I explained that if you are not sure that firing one arrow
at 20 yds gives you a good indication, then fire a group of arrows
at 20 yds, and look at the center of the group of arrows
(center of mass).
Then, I explained, shoot a group of arrows at a longer distance
(say 30 yds).
Then, I explained shoot a group of arrows at a even longer distance
(say 40 yds).
Then, draw a circle around the 20 yd group of arrows,
and mark the center of the circle.
Then, draw a circle around the 30 yd group of arrows,
and mark the center of the 30 yd circle of arrows.
Then, draw a circle around the 40 yd group of arrows,
and mark the center of the 40 yd circle of arrows.
When the center of the 20 yd circle
and the center of the 30 yd circle
and the center of the 40 yd circle of arrows
(regardless of the size of the grouping)
(the circle of arrows for an expert shooter might be very small)
(the circle of arrows for a beginning shooter might be very large)
as long as the center of the 20 yd circle
is directly above the center of the 30 yd circle
and is also directly above the center of the 40 yd circle,
then the centershot is set correctly
for the beginning level shooter, for the intermediate level shooter
and for the expert level shooter.
So, my drawing is not "drawn to scale", that's all.
Trying to explain that walk back tuning can work for every shooter,
and not just the expert shooters.
