Hi Karsten,

Awesome work with these metrics. I am curious, however, why the new
metrics are more correct than the old ones. The graphs are definitely
smoother and including the requests to the Dir Auths seems correct,
but are there other specific reasons for this choice?

Thanks for your work on this!
