Calculates the ratio of 'Favorable' forecasts to 'Unfavorable' and 'Unfavorably Hot' forecasts. A value >1 suggests staffing up; a value <1 suggests minimizing permanent staff and relying on flexible labor to control costs.

Example: A ratio of 2.5 means there are 2.5 times as many high-sales hours as there are low-sales hours, which is a strong signal to increase the permanent staff base and rely less on part-time workers. A ratio of 0.8 means unfavorable conditions are dominant, suggesting the shop should run with a bare-bones permanent crew and use flexible, on-call staffing to cover favorable periods. By defining the ratio, it provides a simple, quantifiable staffing philosophy for the filtered area.
