Do I have finite resources to commit (I know the answer is yes in reality, but how would you like me to think about it?)

Only factor the amount of effort for the individual item. Reality is too complicated to allow factoring in our staffing level, for many reasons:

• We're also required to do work that isn't prioritized by the UREP but is required by the NSF, our proposal, or operational realities.
• We're also responsible for maintenance effort, which is hard to predict.
• We don’t always have to do the work ourselves! (We have partners who often help us out with things that are also in their interest.)
• We’re not 100% sure when our already-underway work will be finished.
