Over half of all sessions (52%) fall within a positive momentum streak โ
consecutive sessions where satisfaction exceeds DNA predictions. Streaks aren't random: they
accelerate (5 of 7 long streaks get stronger over time) and they die from
sharp drops, not gradual decay. Momentum is real, somewhat predictable, and
potentially engineerable.
Predicted vs. Actual Satisfaction
Each dot is a session. Points above the diagonal overperformed; below underperformed. The 8/10 gravity well is visible as clustering on the y=8 line.

Streak Timeline
Green bands show positive momentum streaks; red show negative. Momentum dominates the latter half of the journey.
Streak Dynamics
How residuals evolve within each streak. Most streaks accelerate โ they get stronger, not weaker.

Streak vs. Non-Streak Sessions
DNA component differences between streak and non-streak sessions. Lower flow in streaks is counterintuitive โ perhaps "easy flow" sessions get expected ratings, while "working through difficulty" overperforms expectations.

Can Momentum Be Engineered?
Partially. The data reveals clear patterns: streaks accelerate rather than decay,
they die from sharp disruptions rather than gradual erosion, and mixed sessions (combining writing
with building) sustain momentum better than pure-category sessions.
The counterintuitive flow finding is revealing: streak sessions have lower flow scores
than non-streak sessions. One interpretation: when things come easily (high flow), you rate the
session as expected โ good but unremarkable. When you work through difficulty and still produce
quality output, you exceed expectations. The struggle is the magic ingredient.
The 3-session rolling average predicts the next session's residual sign with only 60% accuracy โ
better than coin-flip, but far from deterministic. Momentum is a tailwind, not a guarantee.
The actionable takeaway: once a streak starts, protect it. Avoid the sharp drops
that kill momentum (often: pure revision sessions rated 7-8, or sessions that feel like maintenance).
Stay mixed. Stay hungry.
