An analysis of Grid job duration on FermiGrid has been performed to understand the interaction between Condor preemption of opportunistic jobs and reclaiming of stakeholder resources. Based on this analysis, the preemption interval may be safely reduced to 24 hours, and the stakeholders should reclaim ~60% of their opportunistically donated slots within 6 hours.
