| Local observability and whole-practice fit | A small feature is easier to measure and change; the wider Work and practice carry other results. |
| Virtuosity and sustainable capability | Technical challenge can expand expression while exceeding bodies, effectors, attention, rehearsal, or replacement capacity. |
| Coordination and local freedom | Partner or ensemble coordination needs shared information; improvisation and expression need room to vary. |
| Participation and precision | Wider entry can increase enactment while simplified distinctions can limit later mastery or style integrity. |
| Visibility and embodied use | Camera, stage, judge, or platform legibility can select features unlike those needed by partners, musicians, or participants. |
| Several structures and one decision | Several architecture views can matter, yet the practitioner still needs one bounded next move. |
| Immediate observation and slower consequence | One occurrence or metric changes quickly; capability, repertoire, selection, and continuation can change later. |
| Improvement and moved burden | A candidate can reduce one conflict while moving cost, risk, attention, exclusion, maintenance, or evidence burden elsewhere. |
