Are you sure this is right? It doesn't make much sense to me, I'm pretty sure it was correct before. Since RTT can be the same as RTT_{min} (i.e., when it is the minimum possible value), we can get a negative precision.

You're right, the previous expression was correct, I've changed it back to the old one.

Nit: try to keep lines wrapped to 80-100 characters max. Ideally, start every sentence in a different line.

Done

You forgot to change the result of the exercise as well 🙃
I've also noticed some more stuff related to the tables that I missed the first time.

Thanks for all the work!
