Quoted from BorgDog:I have not noticed this, but I don't get very many drains from the scoop either.
You could check it manually by putting the ball into the scoop with your hand right as the regular ball saver turns off, and see if the scoop ball saver starts. I'm guessing it won't.
There appears to be something in the code that prevents the scoop ball save from starting if the regular ball saver is still running when the ball enters the scoop (even if there is less than a second remaining when it enters).
