Here is my input:
In the past, the rounds were based on other NADAC classes........ a Weavers round with extra weaves, a Jumpers round with no hoops and many directional challenges with jumps, a tunnel heavy round, a Touch N Go round with extra contacts, etc..............
With that format I think it was very important to make the scoring an accumulation of ALL rounds, as you gave the advantage to the NADAC dog that was well versed in all classes.
If the first seven rounds are all more "Regular" based rounds, then I would see the benefit of leaving it like it is or going to clean slate without a strong lean in either direction.
So if it is put to a vote, I personally would want to know what the "types" of courses will be used in the first seven rounds, as that could have an affect upon a voting decision.
