[time-nuts] Thunderbolt Free-running Freq. Offset

Has anyone established a recommended adjustment window for the Thunderbolt's
10MHz oscillator free-running frequency? Put another way, does anybody have
a feel for how far from "nominal 10 MHz" the free-running frequency can be
before it in some way (if at all) degrades "locked" performance?
I'm assuming that, after power-down, the box looses its 'holdover' memory
and, upon re-power, reverts to zero hold-over correction? Or does the box
remember its last hold-over offset correction despite a power loss?
