All I can comment on is my own experience, but RSV here is pretty damn good. I'm a FLL based guy and bid RSV. I average about 3 days actually flying a month with plenty of Long Call and 1 or 2 days getting released for my last day (finding out at noon the day before your last day that they're giving you the last day off due to plenty of coverage).
My gf is JFK 190 and works 1-2 days a month. She actually dequalified and had to go into the sim two months ago. One week she was on for 4 days, she received 3 days of Long Call and was Released her last day so never even had to go to JFK for 4 days of RSV.
I realize everyone's experiences are different, and not all bases or aircraft are the same. But this is my experience and perspective.
