Can someone help me improve my schematic reading skills? I've reproduced a snippet of a Miami Beach schematic having to do with how the spotting disc influences extra balls. I've got a bunch of uncertainty about this diagram. Here goes:
What do the numbers (50, 1, 5, 32, 6, 12, 31) inside the spotting disc rectangle represent? They aren't the spotting disc lugs, as far as I can tell.
What does "run to top" mean?
What does "run to 1st ball" mean?
In the mixer #3 rectangle there appears to be a "1" in the 9 o'clock position. Either that or it's a vertical slash. What does it mean?
The "E.B. adj. plug" is drawn twice. I believe one instance represents the "L" setting, while the other instance represents the "M" setting. Am I on to something or just lost in the weeds?
Thanks for helping me go deeper.
