Correlating to current measurements, my first Serial log shows up almost as soon as I can see the current spiking from waking up (within a half-second) I haven't timed it super precisely (my off-state is 30 min and my on-state is 4-5 seconds), but definitely going to check this for thoroughly in my next project, which will wake from deep sleep on button press; curious if there's some delay as everything powers on.
