Through more downtime deployments.  My understanding was that we will 
still have downtime when we can't deploy a patch within the time budget.

If that is the case, when we over-estimate the deployment time of a 
patch such that the estimate is over budget but actual deployment time 
is under budget, we will plan downtime that isn't actually needed.
