If that is the object of moving to total time, to increase attendance. I think not.
I see it, as the way Wild Bunch is billed, as a side match at most annuals, most state matches, and Regional s. Only the Nationals (10 stages) and World match's (12 stages) does one see worth in going. Even then it is a physical and mental drain if one is entered in to both events. Due to the back to back shooting, maybe one day's rest to prepare.
Another drawback to shooting the Nationals and World is that the Wild Bunch is shot right before the Cowboy match. How many folks really have 10 days to 2 weeks to spend on food, motels, traveling expenses to do that? Not many. Only the retired RV sector and those few that have the desire to do so. Which may be dwindling.
Separate out the scheduling of Wild Bunch and Cowboy Action Shooting, put distance between matches and that may help attendance. Then again, maybe not.
I had always heard, change a loosing game. If it is perceived that Wild Bunch is in a slow death spiral....Make it worth it to a new shooter to investigate and try it.
