Question: How do you make full use of your long conveyor

l see Team 694 has used a long conveyer on your robot, but this season has a two ball's limit. So, how do you make full use of your long conveyor. If you calculate the number of the ball in your conveyor automatically, how do you do that ( l think it is hard to do because there are so many situations)? And how does your conveyor when you are ready to shoot or intake?
