Hi Red
I am irritated about Your (post-1) "example Score-Reel is on 5 then it only drops to 4" - see here: https://www.ipdb.org/showpic.pl?id=185&picno=39192 the 4673 are Score-Reels --- the 16 I would call Runs-Unit. (Score-Reels are "resetted" beeing stepped forward to reach Zero-Position.) Greetings Rolf
