The Smartclock in difference seems to be able to adapt regulation parameters to its "measurements" of ocxo stability and long term drift.
I do not know any details about Smartclock, but I believe one of the things it does is to adjust the oscillator disciplining parameters (primarily the loop time constant, I suspect, but perhaps more) to allow 3801s to reacquire lock quickly after a holdover event (or at startup), then switch to parameters that reduce the deviation once it is firmly locked. You have to do that manually with a Tbolt if you want both quick lock and best stability once locked.
It may also do as you suggest -- use heuristic methods to tweak the "low deviation" discipline parameters -- but I do not know if that is the case or, if so, if it is better than Kalman filtering.
