Terry,
Thanks for the kind words, and we are aware of the audio issues. As I'm sure you guys know we are doing this with a skeleton crew and last week there were some people in different positions, as well as one person sometime trying to do three jobs. It will be addressed, and I apologize for problems this past weekend.
As for the why wait until the US Nationals, everyone has pretty much explained that. One of the considerations that was also looked at is with the two shot qualifying someone could be put in a very tough position of deciding what call to make. Think about this, you have a problem Q1 now for Q2 you are in a lane you haven't run, and you're not qualified, AND you are trying to win your first TF race. By doing it at the US Nationals they will have two shots to qualify, they will have had one run in each lane, and then they will line up and run for the trophy. It really does make the most sense.
