If I'm understanding the red/green system, with the requirement to have 75% green days at the beginning of open time, that seems to have a similar effect to our DDL (Daily Drop Limit not tied to reserve coverage that applies until trip start -4 days) and DAG (Drop Availability Grid which has defined limits as to how many reserves the company can require for drops inside 4 days up to 0930 the day before) language i.e. limiting the company's ability to deny swap/drop by cranking up the reserve requirement arbitrarily.
