Each dot on the bar is one week of Bryan's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (February 19–March 12), solid teal is swim season, and hollow amber is the closing window ending November 23. The black marker is today — its position against the colors is the entire executive summary.
