So I decided to speed up the process by adding an auto-trigger in the front-end to enable the servo. I updated Guardian and the MEDM screen accordingly.
Now the PMC takes less than 1 sec to lock, and the Guardian finishes after about 5sec.
The initial exponential decay is the intentional lock loss triggered by guardian. The next negative ramp is the Guardian slow PZT ramp, followed by the servo locking transient.
