Band bunching is a term used to describe the band configuration during a shot
when all of the stretch is gone from the bands but they are still in the vicinity of the
projectile. The projectile usually makes it through the bunching without incident
but in some cases the projectile actually contacts the bands on its way to the target.
I do not have proof of this but it is my contention that this band-projectile contact
is the leading cause of the occasional errant shot. I further contend that this
band-projectile contact may be the main reason for many fork hits (the projectile
strikes one of the forks).
