I dont know why just one discard makes the sport more accessible and understandable.
Ah. I think it's because it simplifies the scoring for commentators. Avoids the, "but all these placings will change next race when the next discard kicks in".
BTW: 1 or 2 discards for 12 races. 2 races pr. day make that a 6 day event + measuring and travel. OR there must be more than two races pr. day.
Where did that come from? Nations Cup will be 4 races per day.
