Best stages to macro
Paintmaster (Stage 10, Chapter 1) and Bomb Rush both clear in under 30 seconds with a Level 30 Kamikaze or Chainsaw Battler. Cycle both for the best XP-per-minute.
Clear time budget
Add 7 seconds per clear to your macro timer for the post-match victory screen and level-restart loading. Skipping this margin causes cascade drift over long sessions.
Difficulty + Star math
Tumore 3-Star gives a 20% yield bonus plus the star rating multiplier. Casual + 3-Star is fine for fresh accounts that cannot yet survive Tumore clears.
Efficiency score
Divide adjusted yield by clear time in minutes. Anything above 100k XP/min is strong; Bomb Rush at <30s routinely hits 200k+ XP/min.
