Calculates the average number of 'Favorable' forecasts per unique location in the filtered region. This provides a long-term strategic score for market health, justifying capital expenditure, higher rent tolerance, or expansion priority in high-density favorable regions.

Use Case: If California has a score of 0.8 (meaning 80% of weeks are favorable), and Oregon has a score of 0.4, it clearly shows that California is the superior long-term market for investment, store expansion, and high rent acceptance. This allows businesses to justify higher capital expenditure in markets with proven, data-backed high-demand density, moving beyond simple total revenue.
