Quoted from CactusJack:I believe indicates which rivet number.
It does.
Quoted from CactusJack:I believe that "run to top" means that if it lands on that rivet, it will run the odds to the top value.
This particular snippet is for the EBs - so run to top means you're awarded all three if the mixer #3 is in the appropriate position along with the spotting disc.
Run to 1st does award 1-4 steps on the EB unit depending on the initial position.
The EB adjustment - you have the ability to connect an additional two or four wires in the liberal position. These wires connect to specific rivets on the spotting disc. If you have the liberal adjustment, you have (up to) two more positions to grant the runs to 1st or 2nd EB.
