If your ball launcher has moderately good repeatability, then just take it to the gym and move it around until the poof ball goes into the basket fairly often. Mark that spot on the floor with masking tape.

On show day, drive it all you like, but when shooting time comes, make sure it's driven to the tape marks.... (Maybe you can start there, shoot a few balls, then drive it around - if you have a pickup mechanism, good way to clean up what you just shot. The fire a few at random and be done)

Bottom line: Please the Crowd.
