Pinnacle's rule was once the PBS award was done you could leave your vacation alone and they would modify any trip that touched it so you were still responsible for your trips except what touched vacation day 1. Meaning if you had a 4-day trip and day 3 was start of vacation, you'd be on the hook for the first 2 days of that trip and they would make sure you were back in base. You also had the option to slide your entire vacation period left or right, but if you did so it had to completely cover and/or uncover a trip in order to allow the vacation slide. So in that case, post-vacation implementation after the PBS award was run didn't really help much.
