How to read this chart

Normalized Cycles

Every cycle is stretched or compressed to one full turn.

Rotation compares cycle progress, not calendar days.

Raw Cycles

Cycles start at their halving date but keep their original historical duration.

Rotation remains based on real days since halving.

Historical Timeline

Cycles are shown in real chronological order.

This preserves the actual sequence of BTC history.

Probability windows

Green sectors:

Red sectors:
Historical bottom formation zones

Darker sectors:

Probability windows are descriptive, not predictive.
