Sure is. I've got mine set to 3 balls as well but am liberal on the extra ball settings. Just set another new high yesterday which was 2.3 Mil. Just about got to SWOTR. Had 7 of the diamonds but just couldn't get the Mega jackpot on Rescue to get that diamond. I still have yet to get a mega jackpot.
The new code that's being tested really gives you the opportunity for higher scores. The add-a-ball feature keeps your multiballs going much longer than before. When you stack a Haunted and/or Munchkin mode with a multiball, there's the potential for scoring great bonus points. Throw in a Crystal Ball mode and you're points are doubled. I've had a bonus of over 350K and I've heard others claim bonuses in the 1 Mil range.
I also just recently moved the post on the left outlane which has helped keep balls in play longer. I was getting frustrated with balls just falling into that vacuum sucking lane. I probably averaged one tilt per game just trying to nudge the machine to prevent that from happening. Now about 50% of those hit the rubber on the post and bounce back into play. Had to bend the metal ball guide just a bit to be able to move it to the outer most hole. I know the purists out there probably cringe at my easier-than-factory settings but it's the only way I'll ever be able to achieve SWOTR.
