Merry festivities. I admit I've done this a while ago but never got around to it cos' of personal matters.
1. 8 (〇 → ×).
2. Extend 8 (×), 10 (〇), 16 (△) to MAX. Return from 27 (△□×〇).
3. Extend 485 (〇), 488 (△), 491 (□), 494 (×) to MAX. Return from 509 (〇). To get Max Bonus, you need an early COOL on 494 (×), and a late COOL on 509 (〇) (PS4 version).*
*You actually can get a just COOL on 494(×) and still land the Max Bonus and get a late COOL on 509 (〇) but it is very tricky to do so and I've stuffed up a lot of runs solely because of this last step so I just went for the early COOL-late COOL method.
