Ball scoring system

[Nuttyman54]

It's my understanding that the scoring system counts balls as they go through the goal slots. If they are using a beam break sensor, which seems the most obvious, will it get confused and/or miscount if a large amount of balls is dumped in a corner goal at once (ie. dumptruck style)?

Balls are scored using a combination of real-time ball counters. Balls scored in the Corner Goals are counted by a vision system as they pass over a lighted strip as they enter the corrals. Balls scored in the Center Goal are counted using a photoswitch as they enter the return tube. Additional photoswitches detect balls scored in the Center Goal, but not yet counted at the end of a period, to tell the scoring system to wait 5 seconds to be sure all balls are counted.
