 PRO-AM TOUR EVENT CLAIMS & DIVISIONAL FORMAT CLARIFICATION

Competitors in all divisions must have a minimum of 4 claims from events within the respective divisional schedule. Wild card events may not be used as the only source of in division claims. Wild card events are designed to help competitors living in certain regions, where Summit Pro-Am events are less concentrated, compete for a division championship while keeping costs of travel at a minimum. They are not intended to replace actual competition at the events within a division. At least 2 of the 4 mandated points claiming events in any division must be from events physically located within the division.

Due to its geographic location and the costs associated with traveling to any out of division events, the Border Bandits divisional schedule will continue to be limited to 4 in-division claiming events to determine the end of the season points. As was the case since inception of Division 6, there will be no out of division claims factored into any scores.
