Add option to skip measuring default route

[e0da]

The default route is ALWAYS soooo slow for me. The test takes several minutes to run as opposed to seconds like the other tests. I know that I never, ever want to use the terrible default route. Can you add an option to the script to skip testing the default route? Thanks!

I have been meaning to add an option to skip a chosen route, as I used to have one consistently take a long time as well. I no longer have the issue, but I know it was annoying when it happened.
