Random. Lets say a guy has an 11 day stretch of reserve coming up. At some point before that stretch starts, I see rest assigned about mid way through that stretch. Cool. Now lets say I break up the rest of that reserve stretch using IVD's/PD's/etc etc. Now it's all hacked up, trying to be useless. Can I expect that previously assigned rest period to stay? (Even though I wouldn't need it at this point because the stretch is all broken up). Or can I expect a scheduler to see it's not needed and remove it?
