2. A reserve pilot will not be:
a. assigned a rotation that:
1) will cause his credit to exceed the ALV.
2) will cause his total projected block time to exceed his block hour limit.
3) is scheduled to interrupt a golden day(s).
4) has a report that is less than 12 hours after his release at his base.
has a report earlier than five hours from the end of his last non-fly day.
Exception: A reserve pilot will not be assigned a rotation that has a report earlier
than 1200 (base time) if the non-fly day that preceded the on-call day was a
vacation day.

The two hours prior to ALV is what my Rep and the Scheduler both told me. Heck call them when you are five hrs away and tell them that you want to be shown "Full" for the month and see what they say.
