In addition to what I wrote there... I've noticed that there is a LOT of big scoring that adds up in the background, namely: Rescue Streak and Pteranodon Attack, the latter with a large Pteranodon multiplier.
And of course, use 2x scoring whenever possible -- but I've found that 2x scoring often begins unintentionally, so it's somewhat serendipitous whether you have 2x scoring running at an opportune time. But the good news is: in multiball, you've got a great chance of bouncing around enough into Supply Drop icon standups to qualify your first Supply Drop, which not only adds a ball, but lights your 2x Scoring standup.
If you've got a good Rescue Streak going, and you went RIGHT on initial Paddock, avoid the Spitter and even moreso the T-Rex paddocks. If you go T-Rex paddock, just plan on the T-Rex chowing down on at least one Staff.
I see *completed* modes typically scoring (base, not with Double Scoring):
Control Room: 60-100M
I doubt that most player's TYPICAL Chaos MB or Raptor MB scores are that high, thus the critical strategy of always having either Control Room or T-Rex going PRIOR to starting a multiball.
Last: King of the Island MB scoring gets BIG, in a hurry. As it should -- it's difficult to get to.
