Working definition
Feedback density is how many honest data points you collect per week on what you actually did — not how many outcomes you wish you had.
How it works
Acceleration comes from lead measures: serenity scores, hourly pings, victory journal lines, impulsivity grid ticks. Saying you want a behaviour without scoring it for six months is fantasy with a calendar. Density exposes the gap between story and pattern.
Signature
Six months at 2/5 serenity while claiming block-time discipline — the data is the coach.

Sparse loops versus dense lead data — one dot per month is fantasy; ticks across the week are the coach. Your move: Your move this week.
Your move this week
Add one new feedback loop (score, ping, or grid row) to an existing Battle — do not add a second habit until the first logs seven days.

Deliberate practice requires informative feedback on performance — without valid feedback, experts cannot adjust reps. Density is how often you collect that feedback in your own Battle.
