I say do the same as the nationals at least it eliminates tied points for a round.
At the end of the day either way, to get a good points score and be as high as possible. Take getting BQ for instance, you could have missed out on the A by a minimal margin so if you win the final you get 89 points, guy who qualifed 10th in A finishes tenth in the A gets 90 points so there is only a point difference there.
With the 100,100 ideal same scenario BQ and B final win would mean a total of 178 points , 10th overall and finish tenth in the A would mean a total of 180 points. So BQ loses two points just by being unlucky 11th seems a bit harsh. Especially when there are formula gradings at stake.
I mean the original arguement is that if TQ man crashes out on the firsat corner he will lose out, Well how is that any different with the 100,100 rule? His points surley will still have been affected in the same way. Plus using the 100,100 system means that the person who wins the A final doesn't neccesarily win the meeting, which seems a bit stupid.
At least you get an extra point for TQ to in the one points way if it does go nuts up for you.
