I am having a little trouble understanding what constitutes "default" setting in a pinball machine. In particular I am wondering about my Nascar. I just scored a 498,000,000 point game, and my averages where about 40,000,000 before that. I racked up the max 9 "extra balls" on my first ball! I think I may have had some settings that made it a little too easy to get extra balls. Anyway, I went a head and did a factory reset (and lost my high score ). Now I am looking at my game manual, and many setting do not match the "USA default". I am thinking maybe they were changed since the manual was printed, or maybe I am supposed to change them to match the manual. Is there any info out there that tells you what you should set your machine to to get the current "USA defaults"? Is factory what I should be using no matter what? Thanks!
