If I have 210 widgets with an E(lifespan) of 1 week, and uniform age distribution [0,7] days, with instant replacement, is it reasonable to assume 210/7=30 widgets will need to be replaced daily? What other assumptions are lurking here? Does the shape of lifespan distro matter?

yeah, I want to avoid modeling the stochastic process at the fine-grained level and just do a deterministic substitute... it is a longer time horizon model where week to week doesn't matter much
