This is the BEST explanation of partial reserve days I've seen! Any time a trip interrupts an off day, you need to see when your next 'On call' period begins. Once you have that information, you can do the math for the "10-hours after start" as long as it's on your schedule no later than 12-hour before the start. Otherwise it's 18-hours.
