On my DE Starwars I'd generally expect to score between 150m and 200m. I have the new update ROM coming so I'm expecting a much more challenging game after that.
Capcom Pinball Magic, I kick this game arse  I wish. About 140m is probably average and anything over 400m I'm very happy with myself. Theres generally quite a few games between those ones.
Bally Flash Gordon I only had or a few weeks before I started the restoration but I think my average was about 400,000 hopefully that will improve when I get it back together though.
