Yes exactly:
from Asterisk point of view, re-registration occurs when and only when
a new REGISTER comes in during previous "REGISTER duration", if I may
call it this.

If I'm not mistaken, if you don't forget to also track Unregister
events along Register events, the only missing thing allowing a third
party app to detect re-registration (as defined above) is the
RegistrationDuration data, no matter how useful this knowledge might

Do we agree on that or did I miss something ?

For curiosity's sake, why do you need to detect registrations (and
avoid re-registrations) ?
