Stack Goal
Updated February 28, 2026
Stack goal is the target outcome you are optimizing for, such as sleep, focus, or recovery.
Why it matters
Clear goals improve signal quality and reduce contradictory recommendations.
Goal taxonomy and measurable outcomes
- energy/focus: subjective productivity score and alertness
- sleep: latency, continuity, wake stability
- recovery/performance: soreness and next-day readiness
- metabolism: appetite and consistent pacing metrics
Expected lag and review windows
- acute outcomes may appear within days
- behavioral outcomes often need 1–4 weeks
- deeper performance shifts usually need consistent journaling
Failure conditions and reprioritization
Reprioritize when:
- a goal is not improving after repeated logged doses
- adverse markers worsen consistently
- life context changes dramatically (sleep, medication, schedule)
Practical action step
Choose one measurable primary and one secondary goal per cycle and review outcomes weekly.
Uncertainty and limits
- Evidence is limited on universal lag windows for stacked outcomes.
- Evidence is limited on outcome transfer when contexts shift mid-cycle.
Cross-site references
How this appears in Unfair
Goal mapping drives ranking, reminder timing emphasis, and when recommendations switch from experimentation to maintenance.
Clinical safety note
Any goal-driven escalation with red-flag symptoms should pause until clinician review confirms risk is acceptable.
