I realize there's a large technical challenge involved here, but having the scoring system so physically seperated from the goal in this game format means that teams are getting denied 3-pointers simply because the goal is slowing down the balls. However, since the only solutions involve changing the chains or covering the goal instead of turning off the counter, this isn't going to change this year. So I'll be planning on last second shots not counting for anything.

The make up of the goal sensor array is as follows. There are 6 sensors in the center goal (made in arrays of 2) . one array at the far left of the goal, this one shoots a beam down the slant of the goal and is the senor that keeps the goal "active" during auto and the offence periods at the end if there are still balls in the goal. The next array is in the goal right above the hole, this senor is dual purpose dependent on what period you are in but it's main function is to be the first counter of balls. The last array is directly below the second one but is out of the goal looking at the shoot, this is the final counter for balls.
on each player station side there is a desktop computer which is responsible for interpreting the counting senors (both cameras, and the center goal arrays). That computer communicates with the scoring table computer which projects the scores.
Basically don't worry about balls in the goals not counting.
