My solution to making the regular season actually count is to score the meets head to head like every other sport. Regardless if it's a tri meet or a big invite, or if you run an "A" or "B" team, you get a W or an L against every team you race that day. This creates a regular season record for each team. 15-20 teams make each regional meet based on their regular season record (conference meet included). Top 2 teams at each regional meet auto to nationals. At large bids are determined by a team's regular season record vs other regional qualifying teams (to promote racing quality competition).
