No, the fast speed is where your tracker starts beaconing at the fast rate,
i.e. a purely timed beacon at higher rate.  Only between slow and fast speeds 
does SmartBeaconing work in "beacon every xx miles" modulo corner pegging, and 
then only by scaling the fast beacon rate by the ratio between "fast speed" and 
your current speed.  Above fast speed, corner pegging is disabled and 
everything's just timed at a fixed rate.

Look again at the algorithm on http://www.hamhud.net/hh2/smartbeacon.html, it
doesn't jibe with some of what you've said here.
