Gamorium's take

Touch-rhythm accuracy with a gacha layer that only shapes score ceilings.
the cheat-test profile
Each axis is rated on its own - how far one cheat would trivialize the game here. They don't trade off; low on all four means the game is an experience, not a contest.
cheat: Aimbot - perfect inputs
Full-combo accuracy on dense charts is the real test
cheat: Out-predict an adaptive opponent
No opponent - multiplayer is parallel play
cheat: See what's hidden / map the RNG
Gacha decides your scoring ceiling, not your accuracy
cheat: A perfect solver / coach
Band composition and skill timing tune score output
Each axis is named by the cheat that would break the game along it. Execution is the hands. Reads is out-thinking an adaptive opponent. Variance is hidden information & RNG. Optimization is the solvable systems layer. A game's region is the top one or two axes.
These four aren't one rating split four ways - they're independent 0-10 questions. A 9 on one axis takes nothing from the others, and a game low on all four isn't missing data: it's telling you there's no skill here to cheat.
The basis is how the majority actually plays this game - not a niche mode or a personal run. For a game with very different modes (a story campaign versus ranked multiplayer), that's the version most people mean.
Ranked by shared genre first, then by how closely the cheat-test profile matches - a cross-genre tag means a pick matched on skill profile alone.
