At the end of this month I am shooting to get a reserve carry out rotation into a reg month. Right now my month ends with 2 LC days, vacation beforehand. Am I reading correctly that my spillover preferences will only result in them proffering me something 18+ hours out if I am on LC, and only shorter than that if I am on SC? I thought I might drop an IVD so I only have one LC day at the end of the month, but if my spillover preferences don't waive the 18 hour requirement, then that might be shooting myself in the foot?
