Mooney, the winner of the T2 posted this to rgp:

In case anyone wants to know, the secret was to start regular multiball *and* Time Warp Frenzy concurrently, to get jackpots from both and of course the fresh ballsaver when you start the second frenzy. The *fastest* way to do that is to make three Super Skill Shots, tilting away the first two balls immediately after the skill shot - that lights Super Warp on the left orbit. Lock three balls to start the regular multiball (Time Machine Frenzy), then during that, hit the left orbit four times to start Time Warp. This got me a pile (at least 20) of regular jackpots, two Supers for ~70M each, one Ultra for ~400M, and about 200M in Warp Jackpots... that frenzy lasted for the full five minutes. I had just enough time afterward (about 20 seconds) to lock the fragment for an extra 50M after it ended.
