In my first mail I defined it like this:

----------------------------------------------------------------------
The negotiations should be defined so that all negotiations that use
SKEYID_d (consumes entropy from it) is counted as one negotiation,
those negotiations which do not use it (notifications, new group mode
etc) are not counted as negotiations here.
----------------------------------------------------------------------

I agree that negotiation is bad word for that, perhaps we should use
some other. I don't want to use "quick mode negotiations" because if
somebody add new negotiation that is similar than quick mode then this
would not cover it. 

> Is a notification a separate negotiation?

It doesn't consume any entropy from the SKEYID_d so it is not counted. 

> Is new group mode counted?

It doesn't consume any entropy from the SKEYID_d so it is not counted.

It doesn't consume any entropy from the SKEYID_d so it is not counted.
