We did it based on time...you had x amount of time to hit as many targets as you could but you had to hit all the targets before you could rehit a target for the 2nd time. It cool to have like the top 10 or 5 advance to another round with the same course with less time. A total of 5 buckets is the way to go....doing it this way makes for a fairly long round 1 but then it tightens up after that. Its a lot of fun, I might give it a try :)
