That really depends on your seat/airframe. There is no “permanent” answer.
For instance, last year I dropped my entire reserve schedule each month for a year and picked up open time to fly. Could I do that now, highly doubt it. But I could still probably manage a qtr to half (maybe). It takes patience and work to do that though. It’s not a simple press of the button and done.
