Agreed. With 4 notaries, this wasn't a big of an issue, but I'm noticing with 8, N-1 is more fragile since it's a bigger percentage. (Hmmm, I wonder if percentage might be a good way to express quorum?)

Yes, percentage is how the FF plugin works. It defaults it to 75%

I assume that means 75% of all Notaries known, not just those that responded?

exactly. you don't want to give the attack a chance to influence the results by selectively dropping notary replies.

Pushed to master.
Bug fix related to quorum_duration and quorum_percentage needing to be cast to ints: e52e0de
Most obvious is to be able to set different values for quorum and quorum duration
From Checker.py: Default policy is quorum of n-1 and quorum duration of 1 day
