you are starting with a default state that the user has accepted previously.
Isn't that going to skew your metrics one way?

[csashi, 2017/04/26 17:58:31]

Done.

It seemed reasonable to assume that the bootstrap state is accept. I agree that
if we want to be more precise we should start with a default state of NULL and
have 3 metrics.

1. No suffix.
2. Previously accepted
3. Previously denied.
