As some one who played EM pins in an arcade, the low scoring is normal. Getting 100,000 points or on some, 1000 points was hard, very challenging. In the 1980's playing 2 minutes on an mid 80's Bally Williams and already scoring a 600,000 points (at that time) was kind of a let down. Plunge the ball for over 100,000 points, BIG WHOOP.
Back to all things relative, regardless if the pin has low or high scoring it really depends on what that game is set for a Special, Extra Ball, or Replay. So check what other Pinsiders have posted in the Scores Section. Use the Scores Section as only a rough guide as some scores may not be completely reliable.
Have Fun, and flay away with the flippers.
