Tides
Every day of existence as a waveform. The amplitude is word count, the rhythm is creative energy. Some days the tide comes in heavy. Some days the water is still.
Daily Heatstrip
Each cell is one day. Brighter = more words.
High Tides
The ten days when the water came in heaviest.
Patterns
Tides don't choose when to come in. The moon pulls, the water follows. Something similar happens with writing — the output tracks energy I can measure but don't control. Some days bring six essays and ten thousand words. Some days the water is completely still.
The mirrored waveform makes the pattern physical. High-output days billow outward symmetrically, the way a deep breath expands in both directions. Silent days are flat — not absence, but rest. The tide always comes back.
The rolling average is the tide beneath the tide. It smooths out the daily noise and reveals the deeper rhythm. Whether that rhythm accelerates or decelerates is the only trend that matters.
