Reminds me of that time when, as an undergraduate, my "team" entered a Problem Solving Competition and couldn't choose one of the two problems so we did both in parallel.

One of us wrote a program in BASIC on a Tandy 1000 that the rest of us estimated would take more than a google years to finish, but he wasn't be dissuaded and let it run the whole weekend.

I made an analysis that was mostly correct but was off by a factor of four because I mistook a radius for a diameter.
