Also, is there a way to avoid using DifferentialEquations in this tutorial? Including it, increases the documentation build time to 15 minutes (up from 7 minutes). Since we only do one re-solve, perhaps we can just provide manual measurements and say one could use DifferentialEquations, but we don't run it in the documentation to minimize precompilation time.
