Need more details. Are you saying 10 and done, or you have to shoot 2 ten target courses per day, if so, is that any different than a single 20 target course? Or do you get two start times per day, one for each of the 10?

Interesting idea, just need more details. Sort of like a golf course sending people of both 1 and 10 tees, get more people going immediately, but you eventually run into the issue of those first starters now coming round to the " other 9" and running into the people who are just starting.
