Thanks for the explanation.
In answer to one of your questions, the reason teams should get "penalized", if that is how you want to refer to it, is because they didn't finish in a known position. You're right that the imperfections, (no full field scoring), in the IBCA system create difficulties for points races like this.
I'm not necessarily advocating that we follow along with what the CBBQA does but I think it might help for everyone in on this discussion to know how they dealt with this issue.
In order to keep the playing field between the two types of sanctioning systems level, the CBBQA only gives points to the upper half of the field in both IBCA and KCBS contests even though KCBS has full field scoring. For example, regardless of sanctioning, if a contest has 20 teams, only the top 10 would get points. When there is an odd number of teams, like 21, then the top 11 would get points.
Personally, I am not in favor of points being given when an actual finishing position is not known. I don't mean to be harsh but this isn't T-Ball and we don't have to give something to everyone just for showing up. I also think that it might make people try harder to win, especially in an IBCA contest, if they know they only get points for being in the top half of the field.
Anyone else have any ideas that we can toss around?
