I'm not sure what you mean with this and what you want me to do. Could you elaborate?
That is indeed right!
Actually, I've only improved the performance significantly for bricks with lots of events. The feature you describe have existed since the first version.
instead of relaying all of the numbers in the box, it picks a random number to relay, so for instance [ 1 5-7 9 11 15-17 ] would pick a random event out of 1,5,6,7,9,11,15,16,17 to relay
