Official Q&A: VRC 2020-2021: Change Up

G19 states:

Be prepared for minor field variance. Field Element tolerances may vary from nominal by ±1.0”, unless otherwise specified.

The specification in Appendix A for the distance between the first and second rings of a wall goal is 6.13". By G19, distances ranging from 5.13" to 7.13" are legal. At the lower end of this tolerance, several issues emerge. At 5.2" (within tolerance as specified by G19), it becomes very difficult to descore balls through the bottom. See this video as a demonstration:

Additionally, when the goal is lowered by this amount, it becomes impossible to score three balls inside the goal. This is because the top of the top ball in a goal sticks out past the upper edge of the goal, and since the definition of scored states:

Scored - A Ball status. A Ball is considered Scored in a Goal if it is not touching a Robot of the same color as the Ball and meets all of the following criteria.

• The Ball is fully below the upper edge of the Goal.

The ball is therefore not scored.

Left as is, lowered but technically in spec wall goals have the potential to drastically affect gameplay of VRC Change Up. I ask that the GDC modify G19 to change the tolerance for the hight of the goal rings to 0.5" or 0.25".
