It's a gamble, some will give you extra shots so you can start over under time, but the concept was
KNOW YOUR LIMITS OF ACCURACY
Shoot plate - Hit = Options to Move on or Call Stop to collect points
Shoot plate - miss = Lose all points or in some cases start over while the clock is active.
If starting over, you have until time runs out, without missing, so many will hit the first two or three and stop, some might run out of time and only get one or none.
if they only give you 1 round per plate to start, you have to call it or hit everything, a miss is a 0 stage and that is what people hated, they hit 4 plates, gambled on the last and got a 0 after hitting 4, so they cried.
If you follow current rules of 1 point per hit, that is 5 plates, a 5 point stage it's not outside the limits, but they cried about missing the last plate and losing points for the first.
