Ok. Just did. In order to use PB days with negative RES coverage you must use APD/IVD's. Is there some trick I'm unaware of?

"Insufficient reserve coverage for a normal PD over the days of a rotation or reserve on-call days you are trying to drop will keep you from being awarded a Payback Day drop request. To circumvent this, you may use your Authorized Personal Drop (APD) or one of your Individual Vacation Day (IVD) events to drop rotation(s) or on-call day(s)."
